H1B, Is there a deadline for showing up at the Port of Entry for the first time?

[traveler]

I have gotten an approved H1B petition dated from February and I was also able to get the Visa Stamp in March. However, I will not be able to move to the US till July / August. It could be after 6 months from the start of the petition. The Visa will expire in 3 years time.

Is there a 3 or 6 months requirement to show up at the POE that I should be worried about? Will I be expected to re-apply at the embassy to revise first time at the POE?

i had one year petition and came after 6 months on H1B , so there no problem if you plan to travel in July / August .
