2010年J1签证来美,If 2010 is your first time to U.S. on J-1 visa and you never been to U.S. on FJ before, then the form you use for 2010 is 1040NR, the tax treaty for federal tax applied with no tax withheld. State varies since some state does not grant treaty. 2010年和2011年报的税,估计有错误,想自己再重新审查一遍,应 该怎样弄? You always have 3 years to file 1040X. http://wings.buffalo.edu/intlservices/tax.html Here is a good website with PPT for J-1.
