Oooh yes, not to worry you, but the tourist visa thing could be an issue, eek! They can be particularly unforgiving (I've heard it said the only way you can outstay it is if you're in a coma..) so definitely something to look into sooner rather than later. I don't know how easy it is, if indeed it is at all possible, to extend your visa once you are in the country.
A good place to ask might be on the British Expats website forum - there is a US section which has a special visa section and a ton of very knowledgeable people there who would be able to give you advice if you are completely in the dark. Or maybe your insurers(!) might have an idea or give you the services of an attorney.
Yep, I went to university in Portsmouth as well - 1996 to 1999 and then hung around for about 18 months afterwards until I split with my then boyfriend and got a job in Surrey and now I'm stuck in London, blech. I always love the compactness of the place, plus the fact there is the sea so nearby, and all that countryside just outside too.
I was actually informally advised by hospital staff to do a runner too if my insurance didn't cover it! A runner as in after all the treatment has been given, that is.. not before. Guess it's quite a common thing to do. Really makes one appreciate certain aspects of the NHS for sure, and just what value for money we get. Even now whenever I use an NHS service I get all twitchy expecting to pay, as my US experience really drove it home that you don't normally get something for nothing.
How sad you haven't managed to see any more of the US than this! Hopefully once you've had the little one you'll have a bit of freedom to have a potter about when you're recovered and not at the NICU, even if it's just to check out a few malls and fast food places which are so much better than ours. Think of all the amazingly cute baby clothes you will be able to buy - I love American children's clothes (so much cheaper too) and have cupboards stacked with them from the three visits we've made in the last five years!! Love the place :)
Heh, it's only when you're on constant monitoring like this that you realise just how much variance there is in their activity! Huge range of heartbeat.. which is why I laugh when people say very solemnly that their baby's heartrate was 150 or whatever at their scan like it really means something. Mmm, for 10 seconds maybe it was!
Keep on wittering - we love hearing updates!!
