Wirh respect, that is not a legal position, and I don't advocate doing illegal things. If you don't have legal permission to work somewhere, you are breaking the law. And if you're staying there in six months blocks, you are actually living there.
That is slso a problem when one has kids and one needs them to go to school.
In addition, electronic passports keep track of how often and how long you are in a country.
Again, staying in a country for six months and ten going domewhere else is pretty much impossible for a family with kids.
Yes, many countries give you a six monh visitors vida, but this is not what I am talking as about here.
The only place this works is in Mexicao and the US
