I spoke to Jennifer about this and I apologize for the confusion.
AC-21 is a clues that we use per the USCSI. It is for employees using their old H1B from their old employer to work for SST, meaning that the employee is authorized to continue to work while the petition is being processed for a period not to exceed 240 days.
Hope this makes sense… I am still new in the process, but promise to get it right. =)
Basically, I just really wanted to follow up and check for (I-797A) for both Aravind Malathi Ramachandra and Ramakrishnareddy Gooduru who started work back in 04/13/2015.
Thanks a million
