My wife is a UK Citizen and I did this, this way to avoid us having to spend time apart while the spousal visa was approved or denied.
As long as I am a US Government contractor, I guess that we could stay together in the UK, but then when it ends I'd/we'd have to come back to the USA with nothing.
I'd like to know if I can eventually somehow obtain a spousal visa in the UK based on this without needing to return home?
My Visa reads:
For employment with DOD
Civilian Staff. NATO Contracts
No Public Funds
This is not a SOFA/Exempt VISA. I mention that because it is my understanding that you cannot go from that VISA to a spousal VISA.
I'd imagine that my situation would be the same, but thought that I would ask anyways.
It's a shame we left the UK before they made it more difficult. I had a spousal Visa back in 04-05 and even got an NI number.

Any ideas?
I'd also like to know if I'd be permitted to do side work in the UK with the above mentioned Visa in addition to my DOD contract for a little extra income.
Just questions...thanks!
