For those of you that are thinking about living this experience with your spouse, you need to know how does it work the J2 Visa Process.
As you probably know J1 Visa is subject to a job, so first step is always to find a position and apply for it. Once that you have it, you can apply for a dependent J2 Visa for your spouse at the same time that you are applying for your J1. This J2 Visa will have the same exact duration than your J1 Visa, and he/she will have to pass through the same process than you: filling all the paperwork, going to the embassy for an interview, and once in the USA registering in the consulate and doing monthly check-ins every month.
J2 Visa is intended to be a dependant visa, which means that she/he is just accompanying you during your stay. But once in the country, a J2 Visa holder can apply for an Employment Authorization Document to USCIS, that would allow her/him to look for a job in any field for the duration of your stay. As opposed to J1 Visa, there are no requirements about educational background or experience for the J2 Visa Process, and the company to hire her/him wouldn’t have to sponsor her/him, as she/he would already have a legal status in the country.
The J2 Visa Process to apply for the EAD is not difficult but it takes time to get the resolution (that should be positive if everything is all right). You only have to check the EAD website, send the listed documents to USCIS, a check to pay the fee, and attach a letter stating that the purpose of the job will be cultural and not economical. This last point is important because although the job could be paid you should prove that the salary of the J1 Visa is enough for both to live; remember that the main purpose of the experience is not making money but acquiring knowledge of the American culture, and so the J2 Visa holder has to pursue.
After two or three months you will be receiving your EAD, and then your spouse will be able to look for a job!
