SEPA is EUR only. USD is international wire, a different queue. There are several queues, and you are punished for multiple withdrawals. For SEPA you are punished for very large withdrawals (> 30k EUR) as well, because MtGox are limited by amount/day. For other international wires MtGox are limited by number of wires/day.
I'm just curious how can they be "limited by amount/day"? I understand the various problems as far as different banks having problems but that's pretty instant to figure out. They send the wire and it comes back so they can inform the client that it came back but if they have funds to send no bank will limit your ability to send these funds or am I missing something?
Someone called their bank in Poland and asked about their limits. It is somewhere in this thread. Finding a good bank for a Bitcoin business is hard.
