如何通过婚姻取得美国绿卡
Obtaining Green Card through Marriage to a U.S. Citizen
A lawful permanent resident is a foreign national who has been granted the privilege of permanently living and working in the United States. If a foreign spouse wants to become a lawful permanent resident based on the fact that he or she married a citizen of the United States, the USCIS will approve an immigrant visa petition, Form I-130 - Petition for Alien Relative. This petition is filed by the U.S. citizen spouse and must be accompanied by proof of the marriage relationship. http://www.greencardfamily.com/citizenspouse.htm
When a foreign national marries a U.S. citizen, he or she is considered as an immediate relative of the U.S. citizen. The foreign spouse in the U.S. can file an immigrant application for permanent residence simultaneously with USCIS once the marriage has taken place. The applicant will be required to demonstrate to USCIS that the marriage was entered into good faith and not solely for the purpose of securing immigration benefits for the foreign national.
If a U.S. citizen marries an alien abroad, an I-130 petition must be filed after the marriage to begin the immigration process for the alien spouse (husband or wife). This can be filed with the U.S. Citizenship and Immigration Services in the United States.
