Can I marry my British boyfriend?

Yes. You can marry your boyfriend and he can apply for his residency here in the US if you are a US citizen. He will not need to return to Great Britain in order to apply for his green card.

*Fiancee Petition or K3 Spouse Petition* A Fiance Petition needs to be prepared. This is a petition that will allow your fianc?e 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 fianc?e 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.

Yes you can get married either in England or in the U.S. To get married in the U.S. you simply go to your local court house.

Yes, you can marry and then he can apply for a green card on the basis of marriage. Or, you can petition for him as your fiance and he will get a fiance visa to enter the US and get married to you and then apply for a green card on the basis of marriage.

I am assuming you are a US citizen and that you currently are residing in the US and he is either living abroad or entered the US legally (was inspected and admitted through a US port of entry) and is either currently in status or is now an "overstay" but has never departed the US since initial authorized entry. I am also assuming that you each have the legal capacity to marry (i.e. are not currently married and are adults). Under such assumptions, yes, you would be able to marry and file concurrent petitions for him as the petitioner for his spousal adjustment of status to lawful permanent resident (again assuming he has no other legal impediments such as prior violations of the Immigration and Nationality Act and other applicable statutes which would hinder the process). You should consult an experienced immigration specialist to help you through the complications of a rather lengthy and detailed legal process leading to a family-based "green card" for your potential alien spouse.
