This affidavit documents the cohabitation of two individuals for over ten years without being legally married. It requires an affidavit of cohabitation if you have a roommate, but if like me, you don't, you have to submit an affidavit that you live alone.An I130 affidavit is a written statement from friends, family members, or associates who can attest to the genuine nature of your marriage. This legal document serves as proof of the couple's cohabitation, primarily in the context of legalizing their union or asserting certain legal rights. Two individuals signed an affidavit attesting that they have lived together as husband and wife for over 9 years without being legally married. There is no requirement that the writer must be a U.S. citizen or even live in the United States. Personal Information of the Affiants. Full legal names (though for sample templates, placeholders may be used). I'm a green card holder already and I want to marry my girlfriend in the Philippines so I can petition her and my son. Do not get the terms mixed up because there is an actual form called the Affidavit of Support (I864) which you have to provide too.
