The IRS office serving US taxpayers living or working in Romania is located in Frankfurt, Germany. It provides US federal tax assistance to Americans in Romania. There is no IRS office at the American embassy in Bucharest. There is an office in Cluj that handles Romanian taxes, so they should be able to point you in the right direction.

Don't avoid your taxes, it's too much trouble. The IRS already knows of your bank account in Romania, and if you do not file your taxes for it, you will be taken into Romanian custody. Tried there, and relocated accordingly, which is a completely different process....bottom line, it will take forever.
You would normally fill out the 1040, but get instructions from the Cluj office, or the IRS center in Germany. There are requirements that you need to fulfill to complete your form the right way.
Also ask about form 2555 which includes deductions and exclusions, but I don't know if you are entitled to them since I don't know your whole story, but explain it to whom ever you end up talking to regarding your taxes.
