How do I know if my case is being processed at the TSC or NSC?

The most reliable way to find out whether your EB-2 NIW case is at the TSC (Texas Service Center) or the NSC (Nebraska Service Center) is through the receipt number on your acceptance notice, Form I-797, which the USCIS issues when it receives the petition.

That number, made up of letters and digits, begins with a prefix that identifies the service center handling the case. Because the correspondence between prefix and center can change, the safest approach is to verify through the official source rather than making assumptions.

To track your case with confidence:

• Have your Form I-797 receipt number on hand.
• Use the Case Status Online tool on the USCIS website.
• Consult USCIS guidance to interpret your receipt prefix.

This way you follow the process through the official channel and avoid misinformation from third parties who promise quick results. When in doubt, check directly with USCIS or speak with a qualified specialist.
