Tax Returns Not Submitted after moving out of US

[rvilango]

Hi All,
I stayed in US for 4 years on H1B & had to return back to India for personal Reasons during Oct 2018. i then submitted for Tax Returns during Feb 2019 for year 2018 and i did not submit my tax returns after this, as I did not stay in US after Oct 2018.

I donot have any source of Income in US after this period and obviously no W2.

Am I still expected to submit zero returns without any W2?
Will there be any impact if i need to travel back to US citing the utilization of the balance 2 years of my used H1B period as out of Cap or During my GC processing later.

Please suggest.

If you do not pass the Green Card Test or the Substantial Presence Test for the year, you are a nonresident alien for tax purposes. If you are a nonresident alien and do not have any US-sourced income, you do not have to file US tax returns.

No US income = No US tax return.
