USCIS normally responds to RFE's within 60 days, however they do not have processing times on how long it takes them to respond. It can be longer than that. I would call the USCIS number: 1 (800) 375-5283 and submit a service request, if you do not hear from them soon.
The do-not-call rules require callers that are not exempt from the rules to stop telemarketing calls 30 days after you register a number. There is no deadline for registering a number on the national Do-Not-Call list. There is also no longer any need to re-register a number â it will stay on the national Do-Not-Call list until you cancel your registration or discontinue service.
