This city seems clearly over-hyped in these forums, indeed it is easy to form a company and get residence visa but it really stops there.
Company formation (despite relatively simple process) is incredibly expensive, far more than any other part of the world and full of high ongoing fees for any service or documents you will certainly require for you or your company down the road.
Then, the most complicated, to get a a bank business account is nearly impossible in any of main street major banks of the country, from massive requirements for economic substance, plus large deposits required, plus push for you to︀ buy expensive bank products (like insurance policies, their favorite), plus a huge list of non-high︁ risk activities banned (like consulting, project management, general trading, even real estate if you're not︂ a major co. and don't dare to mention crypto). Even if you are able to︃ tick all these boxes there is a great probability they still won't give you a︄ abusiness account if you are a newcomer with a freezone incorporated company. If you overcome︅ all that, it is a great place to live.
