The reason I mention this: When we were in Oahu Hawaii last year there was a lot of talk about how immigrants with big money were causing already expensive housing and other living cost to soar sky-high. There were feelings and claims that it was pushing the locals out. We sensed some animosity.
Be aware that in some countries our meager US retirement savings may make us look like the wealthy invasion driving their costs higher.
It is something to be aware of even though for the most part your retirement income and adding to their economy will be welcome in most country’s communities.
For some countries, even ones with an accepting culture and people, new tensions may arise when any new US policies play out they see as negatively impacting their country. If you notice any animosity then decide if it will get better or worse as time goes on.
Be sure to find the right welcoming place and get to know your new neighbors.
