I am a U.S. citizen, how do I help my fiancé become a U.S. Permanent Resident?  If I choose the fiancé visa option, how does my fiancé obtain permanent resident status?

 Your fiancé will need to enter the United States with a fiancé visa. Once admitted to the United States with a K-1 visa, your fiancé   will be authorized to stay for 90 days during which you are permitted to marry. As soon as you marry, your spouse may apply for permanent residence by filing a Form I-485, Application to Register Permanent Residence or to Adjust Status, and mailing it to:

    U.S. Citizenship and Immigration Services
    P.O. Box 805887
    Chicago, Il 60680-4120

 My fiancé has a child. May the child come to the United States with my fiancé?

 If the child is under 21 years old and is not married, a K-2 visa may be available to him or her. Be sure to include the names of your fiancé’s children on your I-129F fiancé petition.

 Can my fiancé work in the United States while on a fiancé visa?

After admission, your fiancé  may immediately apply for permission to work by filing Form I-765, Application for Employment Authorization, with the USCIS Service Center having jurisdiction over your place of residence. Any work authorization based on a nonimmigrant fiancé  visa would be valid for only 90 days after entry. However, your fiancé  would also be eligible to apply for an extended work authorization at the same time as he or she files for permanent residence. In this case, your fiancé  would file Form I-765 together with Form I-485 as soon as your marry.

 What if my fiancé  is already in the United States in another status and we decide to marry now?

If your fiancé is in the United States and entered using a visa other than a fiancé visa, and you marry, then you may file an I-130 relative petition for him or her as your spouse. He or she may be able to file Form I-485 along with your petition.

 What if we are engaged but have not yet decided to marry?

 The fiancé visa is a temporary visa that simply permits your fiancé to enter the United States so that the two of you can marry in the United States within the 90 days permitted from the date of entry. It is not a way for you to bring a person here so you can get to know one another, or spend more time together to decide whether or not you want to marry.

 What happens if we do not marry within 90 days?

 Fiancé  status automatically expires after 90 days. It cannot be extended. Your fiancé should leave the United States at the end of the 90 days if you do not marry. If your fiancé  does not depart, he or she would violate U.S. immigration law. This could affect future eligibility for U.S. immigration benefits.
