Hello everyone, I have already read many forum topics on my subject, but our situation is a bit more specific and I can't find an answer. Before I look for an immigration lawyer, I am trying to find the best order for our plan. My girlfriend was born in the US, so she has both American and German citizenship. However, the family left the country after only 2 years and returned to Germany. Now it is our greatest wish to emigrate to the USA together. We are not married yet, but plan to be. Is it possible for me to apply for a Green Card as a partner after marriage? What options do we have and which one is best for us? I have read a lot about the fact that it could be a problem that my girlfriend has no American income and has not filed any tax returns yet. She would probably have to do this for at least the last three years. I would be grateful for any help.
