Just an update on my original question, so we went to see a lawyer, they quoted 36,000 for the visa part, no bank account opening, although they will refer us to someone.
We have two agents with quotes 46,000 and 43,000, and they will open bank accounts and deal with the visa part, same as the lawyers. With the agents, we don't need condo address and the process will take a few days.
Both are providing different services, so for 10,000 or so more I don't need to find and rent a condo in a place where I'm not sure I want to stay long term, and also a much quicker service. I understand the agents are both doing some local magic let's say? Would I get into trouble later on, what is the risk?
