I agree with you, the "how it works" and the workflow are not crystal clear and gives room for suspicion about the validity of the legal advice given. That being said, if the service only gives transparent and actionable information about the visas, it is already huge. I recently had an appointment with an immigration layer for an investor visa. Like any lawyer, he enjoyed drowning me under complexity to justify his $200/hour fee. I ended up with all kind of insider details about 5 different visas... We start from so far when it comes to information transparency in the administration, SimpleCitizen gives an imperfect but still very useful answer.
