Is the case number next to other? if so you can raise a question why it is not approved yet. Mostly it should be a lag from uscis side if there are no RFE’s

@Naveen k yes it is nex to the other. the first one is ended in 21 and the second end in 22

Then I would suggest to call to uscis and ask for update or where the case status is currently at. Mostly you will hear an update in next 30 days.

@Naveen k Do you have or hear a similar cases like me?

Yes but like I said you can raise a query with uscis and it will help you where the case is currently at

@Naveen k I just did. I hope it help us, because the case have just 16 months and uscis say is in normal range.

perfectly normal. they’re different cases, not linked in any way.
