H1 Approved but not stamped. How many months can I wait.

Hi,

My company has filed a H1B for me.

It was picked in the lottery, received a query which was answered and then it is approved.

However, now my company is trying to create positions for me at the client location and is not sending me for the visa stamping. Can somebody please let me know about the number of days that one can wait between H1 approval and stamping. Thanks in advance.

Regards.
