While it seems the problems with funding that arose because the DFG decided to postpone the decision about my Emmy-Noether phase II, are solvable, now the IRS forebodes trouble.
At a visit to the local IRS office to get my "certificate of compliance" I was told I should've filed the form a lot earlier, plus with a whole bunch of useless paperwork. Sigh. Now I'll have to get all that done in no time at all and file it one week in advance, instead of 2 weeks. We'll see what they have to say about that...
