US Immigration from Sierra Leone

Hi. I have a petition pending for i 130 to bring my daughter under age 21. My question is can I submit an expedite request as my child needs to attend school during next academic year.

Hello Everyone,
Finally, last month we received the email from the NVC informing us that our case becoming DOCUMENTARILY QUALIFIED, 7 months after submitting all the requested documents,
Can someone help us to estimate our waiting time from the time our case has become DOCUMENTARILY QUALIFIED and have an interview date (US Embassy in Freetown, Sierra Leone).
If anyone has had the same experience lets help us reduce this waiting pain.
Thanks.

Hello. So my fiance had his interview on the 30th of August for himself and two year old son. After he was asked all the questions, he was then told to bring passport back to embassy after medical is completed for him and son. The problem is that the medical clinic is very unorganized and its frustrating. After three trips to the clinic my fiance was finally able to get his medical results, but of course we are now waiting on the bbys. So he received an email to bring the bby today. They arrived at about 10am and is currently still waiting and its past 5pm and i know that they will be closing soon and they have yet to be seen by the doctor. I dont think it will be completed today and im guess they will have to come back on Monday. It just feel like wasted time. There is no communication from the staff as to what is going on and when other patients ask them, the staff seem to become irritated with them. My fiance hinted at they are probably trying to get bribes from the patients. Which is very frustrating to me since we paid 300$ for my fiance exam and over 500$ for the bby. The bby has yet to receive his vaccination that they claim was part of the requirement for the medical exam. This seems to be the only thing that is keeping us from getting visa processed. Has anyone else had to deal with this during the medical?

Can the k1 visa holder marry someone other then the person that petitioned them? I see on other groups on Facebook were people are inquiring about the process to adjust the status of a work, visitor, or student visa to a immigrate visa mostly through marriage. I always thought that this was against the rules. So it makes me wonder the same about the k1. I research on Google and of course the answer is no, but im wondering if people are actually getting around this rule.

So today my fiance had his interview for himself and the bby, k1 and k2 visa. They only asked five basic questions. Which he answered with no problem. Afterwards they asked if he had completed the medical. He said yes but the results were not ready. They told him to bring the results of the medical for him and the bby once they are ready and to drop off the passports at that time. They gave him a 221g form with the medical results checked. They kept his and the baby's passport photo, birth certificates, and police clearance, But they didn't ask for the affidavit of support form, so im wondering if he will not need it, Or maybe they will want him to bring it back with the medical report. Has anyone else experienced not being asked for affidavit of support at the interview?
