Where can I get married if I don't turn 18 until later this year?

Either marriage, if it complies with the law where it is celebrated, is fine.

You can get married in either place but you need to make sure that you satisfy the requirements for marriage in whatever place you choose to get married. If you get married in the US, you can simply file for adjustment of status to permanent residence once you are married. If you get married abroad, you will not be able to come into the US until after he petitions for you and your visa is approved (9-12 months). Please let me know if you have any additional questions or how I can be of further assistance to you in this matter. I handle these types of petitions for clients nationwide on a daily basis.

Fiancee Petition or K3 Spouse Petition. A Fiance Petition needs to be prepared. This is a petition that will allow your fiance to come to the U.S. in a relatively short period of time. Usually, it takes around 6 to 9 months for the petition to be approved at immigration in the United States. Subsequently, the approval would be sent to the U.S. Consulate or Embassy in your fiance's home country. When your fiance comes to the U.S., you will have ninety days to get married. Our firm can prepare the entire Fiance Petition and make it so it goes smoothly and correctly. You have to have physically seen your Fiance in the last two years. Alternatively, a K-3 Petition can be prepared. This is where you will marry your fiance or have already married outside of the U.S., and then the petition can be approved in three to four months for your then spouse to enter the U.S. Upon entry to the U.S., it would be possible to then prepare and file the Adjustment of Status application. Both the K-1 and the K-3 visas take about the same time.
