Actually @pk, my question was this -
I came to US in 2018 on F1 visa, but I haven't been filing 8843.
So I plan to retro file 8843 for all the years I have been in the United States since 2018. But in 2018 I did not have a social security number, so in the 8843 for 2018 should I put SSN or should I not since I didn't have it at that time?
I'll put my social security number in 8843 for the years 2019, 2020, & 2021 since I have had it since 2019. But just wanted to confirm about 2018.
Also, should I just mail all my pending 8843s to IRS in the same envelope?
