Follow the IRS instructions on how to file dual-status returns. As always, we recommend you seek the advice of a tax accountant.
Prior to leaving the U.S., discuss with your U.S. bank how to keep your account open so your final pay can be deposited, and how to set up a wire transfer for the funds to be transferred to your foreign bank account.. If you have a refund of tax on your U.S. federal or state tax return (or both), you may direct the IRS to deposit the amount into your U.S. bank account. Note that the IRS will not deposit refunds into foreign bank accounts. If you close your U.S. bank account after returning home, and before you receive any tax refund due, you may not be able to cash a check.
The IRS (Internal Revenue Service) can assess penalty and interest and seize U.S. bank assets for repayment. Fines and penalties can amount to more than the original debt. There can be immigration consequences for failing to file taxes. Applicants for a permanent residency "green card" must provide proof of filing taxes for all years of residence in the U.S.
We recommend you consult with a tax professional and with your immigration attorney.
