First of all, welcome to the forum.

Unfortunately, if you're in the US on a dependent visa, you're not supposed to be eligible to work. There is a movement in the US to try to allow "trailing spouses" to work if they are from countries that allow that for US expats - however they haven't gotten very far yet as far as I know.

The option normally cited is to look into doing some volunteer work in the community. Although the work isn't paid, you can often use it as experience when you return to your home country - to show that you haven't been sitting around doing nothing while you're away. Most charitable organizations are thrilled to have volunteer help, and you can always check with local schools, librairies and other public services like that. It's one of the best ways to meet your neighbors and get involved in the community where you're living.
