Nigerians and other foreign nationals seeking to emigrate to the United States through marriage must now pay closer attention to how the US Citizenship and Immigration Services (USCIS) defines a valid union. A marriage certificate alone is not a guaranteed path to a green card or visa benefits, the agency has reiterated in fresh guidance. According to a report by Vanguard, USCIS evaluates every marriage-based petition on both legal validity and the genuineness of the relationship.
Under US immigration law, officers assess whether a marriage was lawfully performed in the jurisdiction where it took place and whether it violates the strong public policy of the American state where the couple resides. Even if a union is considered valid in another country, it may still fail to qualify for immigration benefits.
Five Marriage Types That Fail US Immigration Requirements
The new guidance, issued under the Donald Trump-led administration, identifies five specific categories of marriages that will generally not be accepted for a US visa, green card, or family-based immigration status. These restrictions affect Nigerian applicants and others who assume that any marriage legally performed abroad is automatically recognised.
1. Polygamous Marriages
USCIS does not recognise polygamous marriages for any immigration purpose. A marriage involving more than two spouses is ineligible for benefits, regardless of whether such unions are permitted in the country where the marriage occurred. Applicants in polygamous relationships cannot use those marriages to sponsor a spouse for a visa or green card.
2. Marriages That Conflict With US Public Policy
A marriage may be technically legal under foreign law but still be rejected if it conflicts with the strong public policy of the US state where the couple plans to live. Immigration officers will scrutinise whether the marriage complies with applicable legal and public policy standards before granting any benefit. Possessing a certificate is not enough to automatically win approval.
3. Civil Unions and Domestic Partnerships
USCIS draws a clear line between legal marriage and other recognised relationships such as civil unions and domestic partnerships. If these arrangements are not legally classified as marriages in the jurisdiction where they were established, they generally do not qualify for US immigration benefits. Applicants must prove they are in a legally recognised marriage, not just a registered partnership.
4. Unconsummated Proxy Marriages
A proxy marriage happens when one or both spouses are absent from the wedding ceremony and are represented by a stand-in. US immigration authorities generally do not accept proxy marriages unless the couple later consummates the marriage. Couples seeking benefits on the basis of a proxy marriage must provide evidence of post-ceremony consummation.
5. Sham Marriages to Evade Immigration Laws
USCIS warns that marriages entered into solely to obtain immigration status are not recognised. A marriage must be genuine, legally valid, and based on a real marital relationship rather than an attempt to secure a visa or green card. Authorities conduct investigations where fraud is suspected, and offenders can face visa denial, removal proceedings, long-term immigration bans, and criminal penalties.
What Intending Immigrants Should Know
USCIS stresses that legal validity alone is not sufficient for approval. The agency considers both the legal status of the marriage and whether the relationship is authentic. Applicants are encouraged to ensure their marriage meets US requirements and to submit complete and truthful documentation during the application process to avoid delays, denials, or legal consequences.
The new clarification is part of a broader immigration enforcement push by the Trump administration. With stiff penalties for fraud, the cost of a failed application can be severe, including being barred from entering the United States for years.
Related Green Card Eligibility Categories
In a related development, USCIS has also outlined eight distinct categories under which foreign nationals may be eligible to apply for a green card. These include family relationships, professional qualifications, humanitarian protections, and other circumstances. Prospective applicants must fall under at least one of the recognised categories before filing, according to the US immigration website.
For Nigerians considering marriage-based immigration, understanding these restrictions is essential to avoid costly mistakes in the application process. The safest approach is to verify that the marriage is both legally valid and genuine before submitting any petition.
