回复：Your H-1B was invalid after your O-1 was

Actually, I received the paper approval notice on 05/24/06. The O1 is effective from 04/24/06 to 04/23/09.

It's hard to explain. If My O1 take effective from 04/24/06(the O1 petition approved on 05/10/06), what's my status in from 04/24/06 to 05/10/06, or 05/24/06 (the date I received the paper approval notice)?

Any input is welcome!!

Thanks a lot
