I tried looking this up but I could not find anything relating to these specific circumstances. K1 finally got approved, moved to the US, married in Las Vegas the next month. Have not applied for AOS yet. Here lies the problem. For personal reasons I want to change my last name to my grandmother's last name and my wife would be taking it as well and it would be our (married) family name. I could not find any relevant information about what to do in this situation. Some people have said to just apply for AOS under the new name, some people say your chosen name has to appear somewhere on the marriage certificate. What do I do in this situation? I would really appreciate any kind of help. If possible, I do not want to AOS under my current last name.
