I am a PhD candidate at a US university, considering a one-year post-doctoral fellowship at German institution 'A' right after graduation. Once I get my PhD [and move to 'A'], I would also like to suggest co-writing an NSF (or other federally funded) grant proposal with a professor at a US university 'B' that would potentially fund my post-doctoral research at 'B' after leaving 'A'.
My question is whether my being employed at a non-US institution at the time of grant submission disqualify me from receiving US federal funding for the work I intend to do at a US institution (and the co-PI is at a US institution)?
I checked this and this, but it does not quite cover the above case.
