one of my receipts says "server center : MSC "

What MSC stands for?

Missouri service center. Aka N.B.C National benefit Center.

thanks for your answer, if Im in Texas why would they send my case to Missouri?

I believe the MSC is directly involved with petitions that deal with the LIFE Act. Here is a quote I found about it in the FAQ.

The National Benefits Center was originally created as the Missouri Service Center (MSC), which was set up to process applications associated with the LIFE Act. On April 16, 2003, USCIS Director Aguirre approved the transition of the Missouri Service Center (MSC) into the National Benefits Center (NBC), which greatly expanded the scope of the Center’s operations. The NBC was primarily established to serve as the hub and conduit for all USCIS field offices by completing pre-interview processing of Forms generally requiring an interview. However, evidence of our origin remains, as all Forms receipted by the NBC still bear the receipt number prefix of “MSC.” hope this helps.
