I have a question of the start date on H-1B petition. If the start date on my petition is Oct. 1st, do I need to start work (join company) exactly on Oct. 1st? Someone said the H-1B visa using consular notification can be activated after Oct. 1st, that is, I can join company after Oct. 1st even the date on my petition is Oct. 1st. Is it correct?
Thank you for your answer!
