Definitely, because this sounds SKEEETCHY.  I'd be calling NVC and asking, not waiting around for someone to call me.  Additionally, I'd be looking at all aspects of credit history for dodgy business.  

good to hear that there won't be any issue with traveling, thank you very much for helping me, I was chasing my tale for a while

2-3 months is normal for GC to arrive 

I was also asked to send in another document and passport. Its been 8.5 weeks and still waiting. 

Lots of people are asked to submit additional documents, in particular, the DS-5535 for Canada.
 
No one here can possibly know how long it will take.  There is a very long thread here on VJ for Montreal applicants who had to do a DS-5535, if that is what you were asked for.

Okay, well @Lemonslice went through Montreal, so I'd follow her advice that post-interview processing of additional documents is just slow, and it's not unusual.

Thank you very much!
 

We did it today. Thanks,

You just need to get the Hep A and B started by the time you get your medical done. If not they will not release the medical and you will be on hold until they are started. 

This thread has your answers. 

In two weeks, my family and I have a medical exam scheduled. We recently discovered new requirements for Hepatitis A and B vaccinations, with three doses needed for Hepatitis B and two for Hepatitis A. Unfortunately, we have not received the vaccinations yet, and even if we were to receive one shot now, it wouldn't be possible to receive all the doses in such a short amount of time (typically 6-12 months apart). Has anyone else been in a similar situation??

On VJ? Not to my knowledge.
 
it would not be that logical as the issues are common with other categories 

In general USCIS does take a long time.
 
But for family preference visas, the wait is due to annual statutory limits on the visas.

All sorts of prediction data out there…most say it will be a few years out

 

That was indeed a rapid approval and neither child will be CSPA protected /qualified since they both aged out before priority date became current and there was no delay between filing and approval. 

for their case we should look at table B (dates for filing) since they are in the early stage of gathering their documents and send it to NVC

If you are looking at table B , under F-3 , then you should understand your priority date is not current and even though you can complete NVC documentation and be DQ ….BUT they ( NVC) nor YOU can do a CSPA calculation until PD in table A becomes current. 
Just submit docs and wait and watch
 
And if your sister is now unmarried she can claim F-1 ( current) and push the process 
 

Probably longer than 5 years, as the category is oversubscribed. You can check the Visa Bulletin each month, but between April 2022 and April 2023, F2B has not moved at all and is still at PDs of 22-SEP-15.
