My husband (Nigerian) and I (female U.S. Citizen) met in mid-2019, and began dating in Los Angeles, while he was in the US for the 4th time on a Business Visitor Visa (B1).
After a whirlwind romance, and basically being inseparable, we married at a Chapel (in a mall) in Las Vegas in late November 2019.
We used https://simplecitizen.com/, instead of a lawyer, to file our initial Marriage-Based Adjustment of Status Petition (I-485), Petition For Alien Relative (I-130), Application for Travel Document (I-131), and Application for Employment Authorization (I-765) in Los Angeles, CA on February 3rd, 2020 (we filed on paper, not electronically, and sent it using UPS to receive tracking).
Our I-485 was approved exactly one year after sending it in on February 3rd, 2021!
