Thanks @pk @ErnieS0
My visa is F-1. I have been in the States since 2015 to pursue my degree. According to the IRS, I'm RA for tax purposes since 2020.
There is a 5000$ tax-free income treaty between the two countries. Last year, I forgot to claim it when I did the tax return. Based on the information I found on the IRS website, I could use this tax treaty as long as I am a student.
So, to amend last year's tax return, I know I need to file the 1040-X form, what other forms should I file? And do I need to send my original tax return form along with the 1040-x to the IRS?
Appreciate your help.
