Oh Seto Kamila, you don’t have to file taxes for Last 5 years. Haha don’t be a Sajha lawyer lol. Just filing in 2018 or 2019 would make u eligible as long as you did not hit the cap. I’m not taking for GC or citizenship, but they still have to have earnings in 2018 Atleas. GC automatically file 1040 A. But when u apply immigration benefits , you have to submit your tax transkript, for last 3-5 years for example H1b, dependent visa such as H2, OpT- GC and so on. Don’t tell here so and so , you not a lawyer. A F1 student just arrived here in 2019 November could mistakenly filed 1040 EZ. When they should have filed 1040NR. Things like that. DHS/ IRS knows people file as a resident as because you get various stimulus and work credit and so on. It is fraud to mark as a resident alien , when you are a non resident.
What if you get on a random IRS audit?
