your talking utter BS, every immigration office has a list if requirements for each type of visa, all are slightly different fact. So what crap you are spouting here, where do you recommend he goes and asks? A pharmacy? A flip flop shop? Give your head a shake and get back in your box
How about go to your local Immigration office and ask what your options are and get it straight from the horse's mouth, ever office has it's different take on the rules and will ask for different documents, all you will get here is "think they know it all" people giving yoi conflicting answers so you will be non the wiser anyway
