Marriage to US citizen does not guarantee Green Card: USCIS warns

Marriage to a United States citizen may open a pathway to immigration, but it does not automatically guarantee a green card, visa or any other immigration benefit, the U.S. Citizenship and Immigration Services (USCIS) has warned.

The clarification is particularly relevant to Nigerians and other foreign nationals seeking to relocate to the United States through marriage, as immigration authorities examine not only whether a marriage is legally valid but also whether it qualifies under U.S. immigration rules.

USCIS guidance makes clear that having a marriage certificate is not, by itself, enough to secure immigration benefits.

In certain circumstances, a marriage that is valid under the law of the country where it took place may still not qualify for immigration purposes in the United States.

1. Polygamous marriages

USCIS generally does not recognise polygamous marriages for immigration benefits.

That means a marriage involving more than two spouses cannot ordinarily be used as the basis for obtaining a U.S. immigrant visa, green card or other family-based immigration benefit.

This is particularly important for applicants from countries or communities where plural marriages may be legally or culturally recognised.

A marriage certificate from the country where the union occurred does not override U.S. immigration requirements.

2. Marriages that violate public policy

USCIS can also refuse to recognise a marriage where doing so would conflict with the strong public policy of the U.S. state in which the couple resides.

Consequently, applicants should not assume that the legal validity of a marriage in the country where it was celebrated automatically settles the immigration question.

USCIS considers the circumstances surrounding the relationship and the applicable U.S. legal framework when determining eligibility.

3. Civil unions and domestic partnerships

Not every legally recognised relationship is considered a marriage under U.S. immigration law.

Civil unions, domestic partnerships and similar arrangements may be recognised for certain purposes under local law, but they generally do not qualify for marriage-based immigration benefits unless they meet the relevant federal definition of marriage.

The key question is therefore not simply whether two people have a legally recognised relationship, but whether they are legally married under the rules applicable to U.S. immigration.

4. Proxy marriages

Proxy marriages can also present complications.

In a proxy marriage, one or both parties may be absent from the ceremony and represented by another person.

USCIS generally requires additional conditions for such a marriage to qualify for immigration purposes. In particular, the marriage ordinarily must have been consummated after the ceremony before it can be recognised for certain immigration benefits.

Applicants relying on a proxy marriage may therefore need to provide evidence showing that the couple subsequently established the required marital relationship.

5. Sham or fraudulent marriages

Perhaps the most serious warning concerns marriages entered into primarily to circumvent U.S. immigration laws.

A marriage used simply as a means of obtaining a visa or green card, rather than reflecting a genuine marital relationship, can be treated as immigration fraud.

USCIS may investigate relationships where fraud is suspected and can request evidence demonstrating that the marriage was entered into in good faith.

Applicants found to have deliberately participated in marriage fraud can face serious immigration consequences, including denial of immigration benefits and possible removal proceedings. Depending on the circumstances, criminal penalties may also apply.

What Nigerian applicants should know

For Nigerians considering marriage as a route to U.S. immigration, the message from USCIS is straightforward: a wedding is not the same thing as an automatic green card.

Applicants need to establish both the legal validity of the marriage and their eligibility for the particular immigration benefit being sought.

They may also be required to provide evidence demonstrating that the relationship is genuine. Such evidence can include documentation showing the couple's shared life, depending on the circumstances of the case.

Applicants should also ensure that information submitted to U.S. immigration authorities is complete and truthful.

A marriage entered into genuinely can provide an important family-based immigration pathway, but attempting to manipulate the process can have consequences far more serious than simply having an application rejected.

For Nigerian applicants, therefore, the safest approach is to understand the specific USCIS requirements before filing and to seek qualified U.S. immigration legal advice where the marriage involves complications such as a previous marriage, polygamy, proxy arrangements or questions about its validity.
