BD787,
Will try an answer, ALL PLS FEEL FREE TO CORRECT......
1) You can just tell them you want National terms, but no education or housing allowances.
2)No internal growth on expat as far as i know... may be wrong,
3) Fly on Singapore ATPL, your own licence you renew yourself....
4)Expats are the first to get laid off, then expats on national terms and so on...
5) Basically if not type rated.. No Chance, you have to bring the money with you.
Hope this helps,
OFF to,
RnR...
