TRC is not a holy grail that will protect you, but if you psychologically feel protected with it, you can chase for it.I don’t see it that way. In my particular case, I thought I want to travel a lot. I want to have a low tax place (Dubai with 90 days sounded great) and have some security that my home country will not annoyed me (trc). My plan was to spend 90 days in uae, 2 month in Thailand, 2 months in Brazil, 2 driving around Europe and the rest in my home country.
However, without trc I feel unprotected with my home country as it is in Europe and they are the biggest assholes ever. I broke ties with them but you never know…
It definitely could bring some added value as tax residence proof, but you will need to provide your rental contract and some proof you actually live in UAE if authorities come after you.
Best is to break completely ties, have no assets in your home country, no residence you can live at and just go there on vacation 2 months a year. You can travel around in EU, just keep all proof of your stays outside your home country as there are no border stamps.
So even without a TRC you can claim proof of your residence as long as you can proof you live there most of the time and stay away as much as possible from your home country.
