Non-Resident Alien, Amend

No, you need to wait until the IRS accepts your return and you have received your refund (or your check is cashed) before you can amend your return.  You should go ahead and prepare your 1040NR but do not file it.   You will need to print it and attach it to form 1040X.

You can use the steps here below to amend your 1040 return, after the IRS has accepted your return and you've received a refund (or pay tax due). Once you prepare your amended return,  you will need to mail it in, as amended returns cannot be e-filed. So follow the steps here below to help you fix this situation. 

**Make sure you check the box to show the tax year that you are amending on Form 1040X.

Per IRS page 5 (https://www.irs.gov/pub/irs-pdf/i1040x.pdf😞

To amend Form 1040NR or 1040NR-EZ, or to file the correct return, do the following: 

• 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, etc.). 
• Across the top of the new or corrected return, write “Amended.” 
• Attach the new or corrected return to the back of Form 1040X.
