回複：H1B and H4 Extension after 3 years

The same case here. My school likes to pay the attorney for doing it instead of doing it myself. So, I ted copies of my passport, visa, I-94, three latest pay stubs. My wife's H-1b was filed ourselves and I once planned to file H-1b extension myself, so according to my understanding, you will do almost the same as you filed the new H-1b.
