If you have a large network of social support at home, the option of going back is attractive, both for you and for the baby since here the baby would have no grandparents.

However, this should then be a medium-term goal, AFTER you secure support. Support obligations are very serious - one of the most "serious" types of credit obligations in this country, as evidenced by the fact that one cannot discharge child support debt in bankruptcy and one can even lose a driver's license over unpaid child support. So you basically need to have an official court order for support, some kind of a bank account AND somebody in Boston - say, a lawyer with whom you can email or Skype - to make sure that husband is paying and to call the dept of child support if he stops paying.

So you really need a lawyer, even more so if you plan to go back home eventually.

And if you go back home, I would make triple sure that all support arrangements are official and formalized and that you have a US bank account to which support is transferred. Then it would be for you to wire money to yourself in the home country. Do not let your husband enter into any agreements along the lines of "of course I will be wiring you money" - make the arrangement formal and enforceable, so that you will not depend on his whim in the future. Having a bank account in Boston would make it easy, if your husband falls short of paying the full support amount, to prove to the department of child support that he is not paying. The cost of wiring yourself money is probably $30 per wire; if you wire yourself money once a quarter, it will be $120 per year. A lawyer charges 2-3 times that an HOUR; so if the husband is supposed to send you money abroad but does not do it, you will need to spend several lawyer-hours proving that the husband is not paying. Therefore it is far cheaper to have a bank account in Boston. Plus, if you intend to keep your greencard, you will need to spend 30 days in the US every year, so a local Boston bank account would come in handy any which way.
