Should I make a copy of my tax return?

Always make a copy of any correspondence you send or forms/returns you submit to the IRS or any other U.S. governmental agency, especially an income tax return. You MUST keep the copy of your tax return and all attached forms for THREE CALENDAR YEARS AFTER YOU FILE YOUR TAX RETURN. You should take the copies of your tax returns with you when you leave the U.S. If you return to the U.S. for a future visit, when you apply for a future visa to the U.S., you may be asked to show that you complied with all U.S. tax laws.
