anything affect to my h1b to create the mail alert?

one of my friend says dont create the account as customer link. But i already created the account as customer and gave individual, email id for alert. i dont know my activities are right or wrong?

below my form, i am seeing this information 


OMB control no. 1615-0080

Expiration date 6-30-2012

What is this?

what do you mean by affect? you can always create an account

There is no harm in creating the account to get status alerts.

OMB stands for Office of Management and Budget, which is the part of the government that administers and tracks paperwork and governmental forms (part of Paperwork Reduction Act of 1980). Its not relevant for H1B petition beneficiary (you). The expiration date is related to the OMB.
