Next step after "Post Decision Activity" in H1B Process?


My current status is Post Decision Activity.It shows the following…

On September xx, 2012, we mailed you a notice that we have approved this I129 PETITION FOR A NONIMMIGRANT WORKER. Please follow any instructions on the notice. If you move before you receive the notice, call customer service at 1-800-375-5283.

For approved applications/petitions, post-decision activity may include USCIS sending notification of the approved application/petition to the National Visa Center or the Department of State. For denied applications/petitions, post-decision activity may include the processing of an appeal and/or motions to reopen or reconsider and revocations.

What does it mean? and What next?

Also like to know if there is any timeline for the next step?

Congratulations! -

Your H1B is approved, your employer will get the Approval Notice and you may begin working.
