"You get the student visa & your wife apply as your spouse and then she can work anywhere, not just have to work at the university."
--Well I don't see her wanting to work anywhere but the university. Its a great job, and is why we are moving across the ocean in the first place.
"Your wife can get a work permit (but I'm not sure how likely this really is)"
--I trust a university with a significant international faculty and a strong desire to increase its international reputation knows how to take care of such things. They chose her after an international job search so I don't think there is a problem. She's in one of those fields (computational biology) where the job market is truly world-wide.
"Either way you'll be paying international student fees."
--Actually, as part of her contract they are giving me home fees. Which is really nice! 3,000 pounds vs. 10,000 pounds a year! There's no way they would increase her salary to cover that amount, but it doesn't cost them real money to reduce my fees (they still get my 3000 a year). It works out well for all of us.
I'm going to be busy enough as a postgrad student that I don't imagine I'll be have time to work over 20 hours a week.
I think it will work out either way, but I am worried about re-application hassles. And the "migration" path is a definite consideration for us. We've looked at the official info but, as all probably know, it is quite confusing. I just want to make sure I'm not missing something obvious. Like, can I go to school as a spouse? etc...
