The Main problem is how to get US bank account..then you can ask about the question..NBP can tranfer funds for you but you must have US bank account..
not to bad but i think if someone needs to have a US bank acccount then why does he not use paypal ......how's that ...i think paypal will be the right one but the above mentioned is also not to bad.?
