Wisconsin State Trooper Detained by ICE, Then Released. What Happens Next for Carel Van Der Merwe?

A 21-year-old Wisconsin State Patrol trooper who came to the United States from South Africa as a teenager was detained by U.S. Immigration and Customs Enforcement (ICE) at Dane County Regional Airport in Madison on November 5, 2026, while waiting to board a domestic flight to visit his parents in New Mexico. By the evening of November 6, his attorney said he would be released, and ICE’s online detainee locator no longer showed him in custody.

The immediate detention is over. The immigration case is not. According to his attorney’s office, Carel Aaron Van Der Merwe was released under an order of supervision and remains in removal proceedings before an immigration judge.

This is an individual immigration-enforcement matter, not a class action or compensation lawsuit. Below are the facts, what the Department of Homeland Security (DHS) and his attorney each say, and the federal immigration laws that will shape what happens next.

Who Is Carel Van Der Merwe, the Wisconsin State Patrol Trooper?

Van Der Merwe was born in South Africa and came to the United States with his family around age 14, in March 2019, on a visa that authorized stays until September 2019. According to his attorney, the family filed for asylum and he is included on his father’s pending application. The family has reportedly waited about seven years for an asylum interview. Attorney Marc Christopher told Wisconsin Watch the family left rural South Africa amid attacks targeting farmers.

Van Der Merwe graduated from the New Mexico Military Institute with a degree in criminal justice. His attorney said he wanted to join the U.S. military but could not because of his immigration status, so he pursued law enforcement. He joined the Wisconsin State Patrol on July 13, 2025, and the Wisconsin Department of Transportation confirmed his employment after the detention. He has no reported criminal record.

His attorney says he holds a federal Employment Authorization Document (EAD) valid until 2030. Reporting indicates Wisconsin State Patrol rules allow noncitizens with valid work authorization to serve as troopers.

What Happened at Dane County Regional Airport on November 5, 2026?

According to his attorney, two plainclothes ICE officers approached Van Der Merwe shortly after he cleared airport security and asked for his name. He reportedly explained that he had a work permit and a pending asylum case. Christopher said the officers responded that they “did not care,” then handcuffed him, shackled his legs and took him to Dodge County.

DHS confirmed the arrest and described it as part of a targeted enforcement operation. A DHS spokesperson said he entered in March 2019 with permission to stay until September 2019 and overstayed. DHS used the term “illegal alien” for him, said he would receive due process and said a work permit or pending application does not confer legal status.

The attorney’s account of what was said at the airport has not been independently confirmed. No public evidence reviewed shows how ICE identified him or whether an arrest warrant was used.

How Was Carel Van Der Merwe Released From ICE Custody?

On November 6, 2026, Rep. Derrick Van Orden (R-Wisconsin) contacted DHS Secretary Markwayne Mullin, and his office said the trooper would be released immediately. Reporting from WKBT, CBS 58 and WBAY said Van Der Merwe spoke with Secretary Mullin and that his attorney was told he would be released that evening. WISN reported he was held about 24 hours. His law firm later said he was released on an order of supervision and thanked the people who drew attention to the case, while stressing that the immigration matter continues.

Details the reporting does not establish: the release document, its conditions, and why ICE released him. Reports mention check-ins and electronic monitoring; those conditions have not been confirmed by a public document.

What Is the Difference Between an Order of Supervision and a Release on Recognizance?

Immigration forms matter here. An Order of Supervision (Form I-220B) is generally issued under 8 U.S.C. §1231(a)(3) and 8 C.F.R. §241.5 to people with a final order of removal. An Order of Release on Recognizance (Form I-220A) is used under 8 U.S.C. §1226(a) for people whose cases are still pending. The press describes his release as an “order of supervision,” but the document itself has not been published, so which form was used is unconfirmed.

Does Release Mean ICE Admitted the Arrest Was Wrong?

No. No court has found the detention unlawful, and DHS has not publicly explained the release. Under 8 U.S.C. §1226(a), immigration authorities may detain a person pending a removal decision or release him on bond or conditional parole. Bond determinations can also be reviewed by an immigration judge under 8 C.F.R. §1003.19.

Why Did ICE Detain a Trooper With a Work Permit and a Pending Asylum Application?

The core answer: permission to work is not the same as lawful immigration status, and a pending asylum application does not stop ICE from detaining someone.

How Does DHS Say Carel Van Der Merwe Violated the Immigration and Nationality Act?

DHS says he was admitted for a limited period and stayed beyond it. Under INA §237(a)(1)(B), 8 U.S.C. §1227(a)(1)(B), a noncitizen present in violation of law, including one who overstays an admission period, is deportable. INA §237(a)(1)(C) covers nonimmigrants who fail to maintain the conditions of their status. DHS did not allege he crossed the border illegally; it says he entered with permission and then overstayed. An allegation of deportability is not a final order. An immigration judge decides removability, and available defenses and relief apply.

Does a Pending Asylum Application Create Lawful Status?

No. Under INA §208(a)(1), 8 U.S.C. §1158(a)(1), a person physically present in the United States may apply for asylum regardless of status, subject to exceptions such as the one-year filing deadline in 8 U.S.C. §1158(a)(2)(B) and its exceptions. A pending application is not a visa, a green card or protection from detention.

Pending asylum applicants also do not accrue unlawful presence while a bona fide application is pending (8 U.S.C. §1182(a)(9)(B)(iv)). That rule affects future re-entry bars, but it does not erase a deportability charge based on overstay. This is one reason both his attorney and DHS can describe the same facts differently.

Why Do Overstays With Pending Asylum Cases End Up in Immigration Court?

Under 8 C.F.R. §208.14(c)(1), when an asylum applicant is not in lawful status and the asylum office does not grant the application, the case may be referred to an immigration judge, where the applicant can renew the claim in removal proceedings. That is the path his family’s case would follow.

What Does an Employment Authorization Document Actually Authorize?

Employment authorization for asylum applicants is governed by 8 C.F.R. §208.7, 8 C.F.R. §274a.12(c)(8) and INA §208(d)(2), 8 U.S.C. §1158(d)(2), which sets waiting-period rules. An EAD lets an eligible person work. It does not provide a green card, asylum approval or protection from removal. Employers verify work authorization under 8 U.S.C. §1324a.

Can ICE Arrest Someone at a Domestic Airport Without a Warrant?

ICE officers have statutory arrest authority under 8 U.S.C. §1357(a). Under §1357(a)(2), an officer may make a warrantless arrest of a person believed to be in the United States in violation of immigration law who is likely to escape before a warrant can be obtained, and 8 C.F.R. §287.8(c)(2) sets the arrest standards. ICE also uses administrative warrants (Form I-200), which are not signed by a judge. Whether a warrant was used in this case has not been reported.

DHS described the operation as targeted. A DHS spokesperson reportedly said the administration is working to keep noncitizens without lawful status off domestic flights, and the ACLU publishes guidance on airport enforcement risks for noncitizens. It is inaccurate to say a pending asylum application legally bars domestic travel; the real risk is that travel can expose a person to enforcement. Anyone with uncertain status should consult an immigration lawyer before flying.

Could Carel Van Der Merwe Still Be Deported After Release?

Yes. Release from detention does not end removal proceedings. The process generally runs like this:

1. Notice to Appear (Form I-862): Under INA §239, 8 U.S.C. §1229, DHS initiates removal with a charging document. It has not been publicly reviewed in his case.
2. Immigration court: Under INA §240, 8 U.S.C. §1229a, an immigration judge decides removability in a civil proceeding.
3. Relief: He may seek asylum, withholding of removal or other forms of relief.
4. Decision and appeal: A removal order can be appealed to the Board of Immigration Appeals and then to a federal court of appeals.

No removal date or immigration-court ruling has been reported.

Could the Asylum Age-Out Rule Protect Carel Van Der Merwe After He Turned 21?

This may be the most important legal question. Under 8 U.S.C. §1158(b)(3)(B), an unmarried person who was under 21 on the date a parent applied for asylum continues to be treated as a child for derivative purposes if he turns 21 while that application is pending.

Important limits:

• Under 8 U.S.C. §1158(b)(3)(A), derivative asylum depends on the parent: a child may be granted the same status if the principal applicant is granted asylum. If the father’s application fails, the derivative claim generally fails with it, and Van Der Merwe would need his own basis for relief.
• His marital status and the date his father filed must be confirmed.
• This is not an automatic grant of asylum or status.

Does the Family’s Claim About Attacks on Farmers in South Africa Qualify for Asylum?

Not automatically. Under 8 U.S.C. §1101(a)(42)(A), a refugee must show persecution or a well-founded fear of persecution on account of race, religion, nationality, membership in a particular social group or political opinion. Under INA §208(b)(1)(B), the applicant bears the burden of proof, including the link to a protected ground. General crime or violence is not enough by itself. The attorney’s description of the family’s reasons is an allegation to be evaluated by an adjudicator, not a finding.

Can the Wisconsin State Patrol Employ a Noncitizen as a Trooper?

Federal law bars knowingly employing unauthorized workers (8 U.S.C. §1324a), and a valid EAD establishes authorization to work for an eligible noncitizen. Separate federal, state or agency rules can add requirements for particular government positions. The reporting indicates State Patrol rules permit noncitizens with valid work authorization, and the agency has confirmed his employment since July 13, 2025. The reporting does not say whether he has returned to duty.

Is There a Class Action or Lawsuit Over the Wisconsin Trooper’s Detention?

None is reported. This is an individual immigration proceeding. Detention alone does not establish that ICE committed a crime or violated his constitutional rights, and no court has ruled on the lawfulness of the arrest. If his lawyers pursue a challenge, such as a habeas petition, that would be a separate filing.

• Whether he has returned to work at the Wisconsin State Patrol.

Wisconsin Trooper ICE Detention: Frequently Asked Questions

Was the Wisconsin state trooper arrested by ICE?

Yes. ICE detained Carel Aaron Van Der Merwe on November 5, 2026, at Dane County Regional Airport in Madison.

Has Carel Van Der Merwe been released?

Yes. His attorney said he would be released the evening of November 6, 2026, and his law firm reported release on an order of supervision. His removal proceedings continue.

Why did ICE detain him if he had a work permit?

DHS says he overstayed his authorized admission period. A work permit authorizes employment but does not confer lawful status or immunity from removal.

Did he enter the United States illegally?

DHS did not allege that. It says he entered legally in March 2019 and stayed past September 2019.

Does a pending asylum application prevent deportation?

No. It does not stop detention or removal proceedings, though an approved asylum claim can result in protection.

Was the trooper charged with a crime?

No criminal charge was identified in the reporting reviewed.

Could he lose asylum eligibility because he turned 21?

Not necessarily. 8 U.S.C. §1158(b)(3)(B) can preserve derivative-child status for an unmarried person who was under 21 when the parent applied. It still depends on his father’s application succeeding.

Does release mean the deportation case is over?

No. Release from detention and the outcome of removal proceedings are separate.

Who contacted DHS about the case?

Rep. Derrick Van Orden’s office said he contacted DHS Secretary Markwayne Mullin, and that the trooper would be released.

Is there a settlement or compensation for airport detentions?

No. No settlement or class action has been reported in this matter.

Bottom Line on the Wisconsin State Trooper ICE Detention

The case shows a distinction that is easy to miss: authorization to work in the United States is different from lawful immigration status. Van Der Merwe’s attorney says he did everything correctly, entered lawfully, is included in a pending asylum application and holds a valid work permit. DHS says he overstayed his admission. Both statements can be true under immigration law, and an immigration judge will decide what follows.

He is no longer reported to be in ICE detention, but whether he can remain in the United States has not been decided.
