I am a J2 Visa holder as a "husband" and I know I need an EAD (employment Aythorization Document) in order to work full time. I read the web page carefully but I have a few questions that I would really appreciate if you can help me:
1) The EAD form is I-765. But in the page there are some more that I don't know if I have to fill them, as well. These are: I-485, I-140, DS-2019, IAP-66 and I-94. Are all of them mandatory? Or which one should I or my wife complete?
2) I am planning to work in New York. However, as I have a background in the petroleum industry, I will also want to look something in Houston. So, shall I make 2 EAD - one for NY and the other one for Houston, Texas - or just one EAD, considering that in your webpage Texas and New York should be both deliver to Dallas?
3) I was told I have to start this work permit in United States personally. However, my understanding from the web page is that I can do it by mail. Is that correct? Because it will be wonderful to do it by mail in order not to be 3-4 months in US without working.
I would appreciate if you can help me in any of the questions!
