Service Request Rule + 60 days vs 45 days

1. If you already call USCIS and send a service requeset within 60 days, they won't send another.

2. You can send another service request to get more update on your case within 60 days.

3. If customer service help send a service request, they will tell you to wait 45 days for the reply - generally within 30 days. During the 45 days and the next 60 days cycle, take a rest and wait for the next window open.

This is the protocol they follow for now.

Just my 2 cents
