H-1B vs O-1
The H-1B asks for a degree and an offer in a specialty occupation, and depends on the March lottery. The O-1 has no lottery or cap, but you must show extraordinary ability with solid evidence of recognition in your field. For standout profiles the O-1 avoids the lottery's uncertainty; for everyone else the H-1B is the realistic option.
These two categories differ on 7 of 10 criteria. The full table is below, but if you only have a minute, these are the differences that decide a case.
