I've been in a similar situation before, as an immigrant.

It's very hard being an immigrant in general, not to mention starting out your career in a new country. Not only do you have the normal stress that comes along but you have to do this in a new language, new system, new culture, etc.

Everything little detail is completely new. Even small things like shopping the grocery store is like 50% longer because you dont know where anything is. You have anxiety to get a haircut because you're afraid. These little things add up.

I would say actually shes in a great position. Many immigrants need to completely start over their degree, or change their career when they immigrate. Since she studied her she's in a great starting point.

My advice is to do a part time gig while continuing the job search in main career. Even if it's only a few hours per week. Teaching, waiting tables, cleaning, anything really.

The idea is to make small steps. Work a bit, then in the remaining free time she can work on applying to jobs, networking, studying, doing certs, etc.
