Nobody wants to come to the US anymore, the US is done for at least 10 years. Now it's Dubai, Singapore or HongKong.
Dubai is sliding out the door in terms of tourism and expat population. They won't admit it though. It was already stalling and hotels were not reaching 90% capacity like it used to. Now with Israel being a major butthole, it is trending downwards a bit more. I have never understood the appeal to it. It is like Tik Tok, all flash and cash, but not substance. It lacks a "soul" so to speak. Expats moving here are basically people that have money and are 1) pretentious or 2) have no other option to go anywhere else other than 3rd countries (for whatever reason)
Singapore is holding steady. My favorite city as it is. However, Seoul is taking part of their expat and tourism market at a rapid pace. The two cities are very similar but Seoul is "all that" just as Singapore is but cheaper in many ways. Due to the higher number of people living there as opposed to Singapore. There is a bit more economic freedom in Seoul, but Singapore is still ahead in the GDP. Though Seoul will probably catch up and surpass it in 6-8 years. They have already grabbed the title of the biggest performer in the world for most popular plastic surgeries. (facial, lipo, cryolipolysis, nose, eye lids). Their medical care is top notch. This is the biggest concern for people moving to other countries. The only draw back is if Seoul decides to implement a COE program for car purchases like Singapore. Basically you have to buy a 10 year permit to own and use a vehicle in Singapore. The cheapest permit for basic cars like Kia, Hyundia, Honda, etc.. is about $60,000 if I recall correctly. Luxury vehicles like Mercedes, BMWs, and SUVs are more. About $90,000. To be clear, you have to purchase the permit and THEN buy the car. Those 60K and 90K price do NOT include the cost of the car. You still have to pay the $30K or whatever the car costs. And it is only for 10 years. And you have to enter into a lottery type system to get one or either you have to enter an auction/bidding type sale.
Hong Kong brags about the increase in new residents that they are getting. What they don't tell you is that the vast majority of them are from mainland China. This will not last as the people are leaving that area to move because they want a bit more freedom in their lives and recently Hong Kong has been tightening the noose so to speak to bring the city closer to the political, economy and social ideals of Beijing.
