S2000

Hello,
Vietnam Airlines will pay me 100% for my school in USA, but i have to sign contract & work with them for 5 years and my monthly income is STARTING OUT at $1,500 USD per month. I start working with them immediately after i finished my school (CPL, IR, MCC, ATPL...), its gonna take around 24 months at fly school in USA + fly school in Vietnam. Total they have to pay $120,000 USD, do yah think thats good for $1,500/month (start out) for 5 years contract ? What if i signed the contract but i don't work for them ? i go look for a different airline in USA is that ok ? or do they gonna take me to court & make me pay back $120,000 USD ?

Thanks alot every1.
