How to prevent immigration marriage fraud.

Protection starts before any immigration filing is made. The six safeguards on this page — independent legal counsel, background investigation, social vetting, premarital counseling, a premarital agreement, and a pre-immigration agreement — are designed to be implemented before irreversible legal and financial commitments are created. The most important step is consulting an attorney whose sole obligation is to protect your interests as the U.S. citizen sponsor, not to expedite the immigration process.

Yes. Most immigration attorneys are trained to secure immigration benefits for the foreign national, not to protect the U.S. citizen sponsor. Their interests may be structurally adverse to yours. Independent legal counsel means an attorney who represents you exclusively, advises you on your financial exposure under the I-864 Affidavit of Support, and helps you understand the legal consequences of sponsorship before you sign anything. This is the single most important safeguard against marriage fraud.

A pre-immigration agreement is a written understanding between spouses that defines expectations, responsibilities, and conditions related to the immigration sponsorship process. Unlike a prenuptial agreement — which focuses on asset division in divorce — a pre-immigration agreement addresses immigration-specific concerns: cooperation with the process, truthfulness in filings, consequences of abandonment, and financial responsibility boundaries. It is a relatively new concept and should be drafted with an attorney who understands immigration fraud.

The I-864 Affidavit of Support is a legally binding contract between you and the U.S. government in which you agree to financially support the foreign national you are sponsoring. This obligation can last indefinitely unless, among other things, the sponsored person becomes a U.S. citizen, can be credited with 40 qualifying quarters of employment, or permanently departs the country. Critically, this obligation survives divorce — meaning you may owe financial support to a former spouse who defrauded you. Understanding this exposure before signing is one of the most important steps in preventing marriage fraud.

True due diligence goes beyond what you can find in a Google search. A professional background investigation may include identity verification, criminal history checks, immigration filing history, financial records, social media analysis, and interviews with references in the person's home country. This is particularly important when your partner has a complex immigration or relationship history. The goal is to verify that the person you are considering sponsoring is who they claim to be, before you assume irreversible legal and financial obligations.
