If they pay using PayPal, the money will simply be in your PayPal account. You can change currencies in PayPal. I have been in the reverse situation, being paid in Euros by a European MSC. It was very easy.
If they want to send you a check, it will be costly for you to cash it in Europe. If they want to pay by direct deposit into a bank account, they may accept your Swift number (I think that is the right term).
Ask the MSC for options.
