You should have received a packet that sets forth the full process for adjusting status after marriage in K-1 status, which you should follow.To the best of my understanding, you must file an I-485 petition to adjust status; you will need an Affidavit of Support on Form I-864 as well. No I-130 is required if you got married within 90 days of entering the US in K-1 status. Filing for EAD on Form I-765 is optional, but most people do it because EAD petitions are typically adjudicated much faster than I-485 petitions. All of these forms should be filed before your K-1 admission expires (90 days) or you will go out of status and will be at risk for deportation. Ideally, you would have filed the petitions on the first business day after you got married, but I would imagine that youu2019ve already blown through that preferred time frame.
