I am a postdoc in a US university (Rank A, edit: R1). I tried to get an academic faculty position in the US, but was unsuccessful. I got an offer (lecturer in the UK system) from the UK university (say, Rank B, edit: "new university"). Is it worth to accept the offer, and again try from the UK to get a faculty position in the US? Or I should try to get another postdoc in the US only? Would it be difficult to get the position once I move out from the US?
I have gone through In order to get a CS faculty position in the U.S, should I have a Ph.D. from an "American" university?, Is it more difficult to score a Tenure Track position in the US when applying from outside?, and What should a faculty member outside of the US do to move to a top-tiered American university?. But still not sure in my case.
One of the reasons of not short-listing is that I do not have a PhD from the US, (I thought). I got only two on-campus calls (from college/new univ. only) for the interview out of many.
Any suggestions? Thanks in advance!
One important issue is being able to get to an on-campus interview. Although prestigious research universities would often be willing to pay the cost of flying from the UK to the US for an interview, many other institutions (regional comprehensive universities, four year colleges, and lesser ranked research universities) might not be willing to reimburse you for the cost of travelling to the US for an interview.
If you're interested in positions at these less prestigious institutions and aren't prepared to pay for your own travel expenses then you might have trouble applying from the UK.
I think the more important question for you to consider is whether this lecturer position in the UK would give you better experience than continuing as a postdoc. That depends on what other teaching experience you have and the kinds of positions that you're applying for.
