That's what happened to me back in 2021. There was a program for reunification of fiancées during COVID. I applied for my back then fiancee for her to join me , and there was no enough evidence that she will go back to Morocco. So why did they do this sort of application when they were going to process it like a tourist visa. I don't get it. The reunification is for Already married spouses to join their family and make it easy, but if it goes back to the TRV file, then there's no point in wasting time and applying again. Honestly there's no enough evidence to show that they will process it faster. If it falls back to the case processing office in a particular country, then it goes back to the same pile, and you will keep on waitingI remain doubtful about the whole thing.
Have they created a special TRV application process for family reunification? If not, anyone applying on that basis will simply be sending off what appears to be an ordinary TRV application that will be tossed on the pile, awaiting a decision and unless it gets a hard look (which almost never happens), the visa officer won't even recognize it as seeking family reunification.
