Subhumans guitarist Phil sent this in to us this morning regarding their cancelled US shows:

Hi Guys,
Subhumans visas finally issued today in London, so by the time we get our passports back we should be in the US on tuesday for the Pittsburgh show and the rest of the tour. We're planning on coming over to do all the shows we missed next spring, and later next year we'll be out on the West Coast. The visas are valid for a year so there won't be any similar problems occurring.

As the band is traveling they haven't been able to get this info up on the Subhumans / Citizen Fish site as of yet.
