I agree with the Skipper. If you must go, try EVA. They didn't lay anyone off last year. CAL laid off lots, and ALL for foreigners who thought they had some protection of experience, or years of service, or extra work in the office. Capts were mere months away from collecting their 200k+ pension allotment after investing 10 years, but CAL let them go so that they wouldn't reach it. This is common practice for CAL.
Also, you cannot become a national (ie: Passport) even if your wife is Taiwanese. Permanent resident and "National" are 2 different things. Only Nationals are protected under the labor laws of Taiwan.
If you were on a national contract, you would not get housing pay, and you would be flying a Heavy 90 hours a month for 3k gross. You really want to put your family through that? You may like it here, but you wont for that kind of take home pay.
Good luck.
