How would this work?

I may be wrong here, working on personal experience only, but I have never seen a dental assistant perform any function other than prep materials for the dentist - never get into a mouth.
Not been to the UK for over 7 years, but I don't suppose that'll have chanced.

I also know the UK's dental services are a mess.
Assuming your lady wife is legally allowed to work in the UK, I'd get the phone and call a few dentist, asking about potential work.

Skype with a UK landline package would keep that cheap, and you'll get numbers here.

Thanks Fred- I'm going to do just that! I guess if the dental field is a no go she would want something part-time mornings preferably 8-8:30 to 12-12:30ish any ideas to keep her busy and working in a somewhat decent job? ALSO TAXES I haven't spoken to the company expat people yet but any idea how that works? I will have to pay us and uk tax?!

I understand all US citizens have to pay taxes to the US over a given amount, and you'll have to pay UK taxes.

If she's legal to work, she'll be issued with a temporary national insurance number, paying UK taxes starting with her first salary.
UK tax is only paid after a given amount earned, and a part time worker may not get that much.
I'm way too far out of date to know the numbers.

Great thanks Fred - looking into the 7 year domicile exclusion - any ideas on a decent part time gig for the morning hours?
