Hi, and welcome to the forum. I grew up in the Boston area and go back there a couple times a year to visit, so I'll try to be of some help here.

First of all, have you got the matter of visas sorted out yet? Or are you looking for jobs to find a sponsor for your visa applications?

If you've got the visa situation in hand, you'd probably do best to wait until you arrive to start looking for jobs. It's a little bit early to be looking for work if you can't start until next January - and very few employers will hire anyone sight unseen. Besides, any potential employer will need to verify your visa status before they can hire you - and that can't be done until after you have entered the US and received (or at least applied for) a social security number.

If you're looking for work to find a sponsor for your visas, you pretty much need a university diploma of some sort, and to offer some sort of skill or experience that is not commonly found in the local population and is in demand (preferably by a large employer, who has some experience with hiring from overseas). This normally means that one of you would have to be a managerial person or someone in a highly technical profession, like an engineer or IT person.
Cheers,
Bev
