If you were born in a foreign country to a U.S. citizen parent or parents and your parent did not register your birth in the form of a Consular Report of Birth FS-240, you may apply to a U.S. passport agency for a U.S. passport (proof of citizenship), or, alternatively, to USCIS for a Certificate of Citizenship to document your U.S. citizenship.

The U.S. citizen must file a fiancée petition, Form I-129E with the local U.S. Citizenship and Immigration Services (USCIS). The USCIS will forward the approved petition to a U.S. embassy or consulate abroad. The post will then contact you with information and eventually schedule an interview for a fiancée visa. You have 90 days from entry into the U.S. in which to marry the U.S. citizen, and you must leave within this time if you do not apply to become a permanent resident.

No. After the marriage takes place, your U.S. citizen spouse must contact U.S. Citizenship and Immigration Services to change your status to legal permanent resident. This information is given to you when you enter the U.S.
