So here's the situation breakdown.

• I'm British, wife is Thai
• Both permanent residents of Canada
• Wife still has FLR status from UK
• I work full time and she's in full time education

Wish to visit either San Antonio, Texas or San Francisco, California as part of a business trip, would like the wife to accompany me.

I was wondering if anyone else has applied and had any success?

Should be fine.

You both live in Thailand? You with a work permit?

When she goes to the interview she should have your passport, with the Thai visa extensions flagged, and you r work permit. These'll show you're established here and the probability is that you'll return after the U.S. visit. Your wife will probably return with you, but your status is the key.

I took it to read that they're living in Canada, Canadian PR and posting from Canada.

Macs comments still apply though, ties to Canada and thus a good reason for both to return, I suspect there would be no problem, but as Mac says ensure that she presents evidence of both of your ties to Canada.

Correct. I'm going to get my apartment lease amended to get her name put on it and she will have a letter from her college.
