H签证能不能读书？

I asked the same question to an immigration lawyer. Theoretically it's possible. You can full-time study and part-time work, only if your salary reach the minimum requirement for the postion of your H1-B. In practical it's mission impossible, unless your employer is very supportive and is willing to take risk to make paycheck for you.

多谢两位师兄指正。 偶的一个朋友正在转。 他要从H转成F。
