Can a U.S. Bank check be deposited in a Polish bank account easily?
Easily? Not really. Many people here don't even have branches, just an electronic account. I'm having to go to the main branch of PKO to deposit checks from back home, and some of them take quite awhile to process, as they actually SEND the check back to the states to secure the funds. Plus they charge a minimum fee of 20 pln or 1.5% of the amount, whichever is greater. Try PayPal. It's fast, painless, and cheaper.
