I am a PhD student in the USA on F1 visa married to US citizen applying for green card. Today we have submitted application I-130 online (through account with USCIS). Now if I understand correctly, I can apply for form I-485 in the meantime/concurrently? Download it, fill it out and mail it together with other documents before getting I-130 decision? I read so on USCIS website, but just making sure I have this right. Thank you!
