Does Spain need immigration supervision for pre-1+2+2 visas?

I don't know what you are talking about. If you can get a work permit in Spain, you generally have to continue to live legally for more than five years before you can obtain long-term residency. The first year is to work and stay for one year, then two years, then two years, and finally you get permanent residence.

The Spanish immigration law clearly stipulates that a person who has obtained short-term residency in Spain may not live abroad once or continuously for more than six months within the validity period of his residence. It is generally difficult to successfully continue to stay in violation of this regulation.

Even if you get a long-term residence, you are not allowed to live abroad for more than 12 months at a time, which adds up to more than 30 months (within the five-year validity period of the residence card).

In addition, it is almost impossible to get a work visa in Spain now, because the Spanish consulate here only issues visas for some special jobs, such as doctors and seafarers. Whether it's a nanny, a builder or a chef. These non-technical or low-tech jobs are currently impossible.
