my views:
1. you should get input from your US hu*****and.
2. don't just calculate medical expenses. math. some times is very miss leading.
3. if your hu*****and must return to USA. the best choice for you is follow him to USA.
4. birth experience in US hospital is very relaxing family like experience with your hu*****and at your bed side all the time.
5. US do have good medical system for you and your new baby both both before and after birth.
6. language is not a problem. your hu*****and is with you during the birth all the time. and also has interpreter (chinese or japanese)
7. last but not the least: forget about Math. , passport and money. think about health for you and your baby, think about family union at this special time.
