Im going married my boyfriend but he doesn't have ducument he came legally to the usa with a visa but it had expired 4 year ago. What should i do..

Hello Joanna. If you are a US citizen, and you marry your boyfriend, and he entered the United States with a visa, then you can sponsor him for his green card, and he can process his case without going back to his country. This is true despite that he is out of status now. Some of us charge a very affordable flat fee rate to handle the case from start to finish.
