1040 instead of 1040NR-EZ

Yes, when you are a non-resident you will have to file form 1040NR. If you filed already then you will have to file an amended tax return (1040X) and send in the correct form 1040NR. You have 3 years from the date you filed your 2018 return (or 2 years after you paid the tax due, whichever is later) to file an amended return. You will have to download, fill out and print Form 1040X: https://www.irs.gov/pub/irs-pdf/f1040x.pdf 

Please follow these instructions:

• Enter your name, current address, and social security number (SSN) or individual taxpayer identification number (ITIN) on the front of Form 1040X.
• Don’t enter any other information on page 1. Also, don’t complete Parts I or II on page 2 of Form 1040X.
• Enter in Part III the reason why you are filing Form 1040X. 
• Complete a new or corrected return (Form 1040NR). 
• Across the top of the new or corrected return, write “Amended.” 
• Attach the new or corrected return to the back of Form 1040X.
