I recommend you do premium processing. you'll get a response in 45 days.

if you’re very sure in your case you can do premium processing or try to send a request and inquiry

I am asking about any idea how long it will take in regular processing. If anyone has recently got approval in regular processing via NSC. I know about premium processing. In my question, I did not ask about alternative. I asked about any guess of timeline. Thank you!

have you tried a service request?
