Naya Nepali bhai or buini,

All you need to do is fill out the form 8843 and mail it to the irs address.

1. Go to irs.gov and search for form 8843 (search is on the top right hand cornor of the page).

2. Download the form and fill out the top portion, section I and III only. You provide the information that you know on these sections that are related to you.

3. Sing and date the form on the bottom of second page.

4. Mail the form to the address given on the instruction. Read the instruction for that. Instructions are below the form.

This is very simple and you will be fine with US tax law if you do as I have mentioned above.
