I don't think it's common for those adjusting from F-1 to get approved on the spot. They need to review our immigration history and that probably takes time. Some people had to wait for a few months, even though their I-130 was approved. You just never know.

just that there is a congressional unit in every office whose jobs is to attend to congreswoman/men's queries. papers get processed from a storage in uscis and each IO will scan a few files to themselves and they get judged on how many cases they process. sometimes your file might be with someone who checked it in and then went on vacation but forgot to chekc it out. so basically it;s sitting on their desk waiting to get approved. which is what i was worried about! and that's when it helps to get help. Also when you expedite it , it will get removed from the pile go through expedite and put back into the expedite processing. so when your congressman/woman investigates it helps to first just enquire on the case because if it is processng normally then why expedite it. now if there are bumps after they hear back , you can expedite it if you have a valid reason

Update!!! 
 
Had my interview today it went well took us less than 10 mins only question she asked questions about who brought my son into the us and who he was living with when He was still in a Jamaica. She said she is going to order the greencard to expect it in 10 business days. My status hasn't been updated online yet. 
 
All the best for the rest of your journey. 

From what I've researched, your (our) next update will  be 'ready to be scheduled for interview.' Which means our field office has received our file, determined everything was ok and put us in the line for interview. After NBC received the RFE response, it was waiting in the pile with other responses, then scanned as 'received,' went to the officer's shelf, he/she reviewed it, continued working on our case. If no other RFEs, he/she put it in the line with completed cases to ship out to field offices. They mail it to our office, there it sits again before they review it. They finish the checks and put in the line for interview. The timeline varies office from office. If your office is busy, it can take weeks/months to get to this stage.
