yes, I've seen a lot of those, and how people can be denied or deferred a visa based on mental health history. What I hadn't seen mention of is the requirement to obtain a medical report and the actual length of time it can take. People without a mental health history don't need to obtain a medical report, so few people have to go through that.
I thought the embassy decides if someone is mentally fit or not based on hospital records or a letter from a psychologist, but its a specialist from the hospital that has to create a report for that, and that report can take weeks or months to complete.
