I happen to be in the similar situation as you; I have two dependents and I plan to teach Mandarin in Intl School abroad. But instead of pursuing QLTS (for further education, not school), MA in Intl Edu and MA in TCSOL, which are NOT required by Intl School recruiters, I will do PGCE amid plenty of obstacles ahead including long travel distance to uni & schools, requirement to take GCSE English, etc. A friend of mine, who can teach both Mandarin and Spanish languages and equipped with a Masters in Education from HK, said she tried but failed to secure employment in Intl Schools. Recently she has been accepted to take PGCE in UK this Sept. So I strongly suggest you to reconsider your plan.

Alternatively, you can also consider teacher training providers in other nations, for example, Singapore MOE's PGDE, HK PGDE (I heard it is much easier than PGCE), Fairview Intl School (IB school) in Msia offering 3 years contract in work and study (IB training + Singapore PGDE), or PGCEi from Sunderland/Nottingham Uni (online, may be accepted abroad not UK).
