Immigration Law Questions? Ask an Immigration Lawyer.
Hello: This is Attorney Phillips. Welcome to Justanswer! I am reviewing your post, and I will post my response very shortly. Thank you for your patience.
Once you get married, you file Petition for Alien Relative (form I-130) for her. Once that is approved, you can file Application for Adjustment of Status (form I-485 Green Card Application) for her. On the other hand, you can file both I-130 and I-485 at the same time. Once the I-130 is approved, her immigrant visa becomes available and you can thus file the Green Card application for her.
If you do not have any follow-up question(s), kindly give a positive rating to my response so that I can receive credit for responding to your post. There is no additional cost to you for doing this.
Thank you for your cooperation.
