Hello! Thank you for your helpful answer.
I have a similar situation, but I have already left the USA (I am not the resident), and filled the form wrongly 1040 instead of 1040NR. I quite get what is the procedure to correct it, but did not get where to mail the forms.
And additionally what are the consequences of not correcting it at all? Will I have troubles with IRS or some sort of it?
Thank you. Regards.
