Can I go to other EU countries with a Spanish residence permit?

Permanent residence and family residence are two identities of foreign immigrants in Spanish alien law. According to this law, permanent residents will enjoy the same life and work rights as Spanish citizens. In other words, you can engage in legal work in all parts of Spain, including running a job or business by yourself. These rights are still limited to Spain. The EU has the same laws and regulations in economy and politics. However, each EU member is still an independent country. It has its own laws and regulations in many aspects. For example, every country's immigration laws are different, and those who hold a country's legal immigration status can only have the rights conferred by the country's immigration laws. So you have a Spanish immigration residence permit, and you can only have the rights and freedoms granted by Spanish immigration law, including free migration between Schengen countries. Last but not least, it is stipulated by Schengen countries. In other words, people who hold the legal status (or visa) of foreign immigrants in Schengen countries can freely enter and leave Schengen countries within the validity period of this document, which does not mean that they can stay or work in these countries.

Many overseas Chinese have misunderstandings in this regard. For example, many overseas Chinese living in Italy or Portugal stay in Spain for a long time, and even open their own shops, companies and find jobs. In fact, this is illegal. Overseas Chinese living in Italy, France and Portugal can directly enter Spain without another visa, but according to the provisions of Spain's Aliens Law, their legal stay shall not exceed 90 days. Because there is no "national border" when entering Spain, there is no border checkpoint, and there is no entry and exit stamp on the passport, it is generally impossible to tell whether it is legal to stay.

But on some specific occasions, the police can ask you to show your entry documents (such as air tickets and registration cards). For example, if you want to get a foreigner identification number (NIE) in Spain, you must prove that your stay in Spain is legal (no more than 90 days from entry). Although you can stay for more than 90 days, there is generally no problem, but you must not work. The boss of a company established in Spain can appear in the company as an investor (boss, shareholder), but he can't work as a boss. It is precisely for this reason that a company whose boss or shareholders are foreigners (including overseas Chinese) who do not have legal work and residence permits in the West must hire legal Spanish nationals or legal immigrants to run the company's business as managers and supervisors, including hiring other workers. Spain is like this, and so are other European countries.

I don't know the specific provisions of the immigration laws of other countries, but if you want to go to other countries to develop, you must obtain the legal status of that country. It is said that in a certain country, people with permanent residency in Spain are allowed to live or work (I have heard about it, but it has not been confirmed). Even so, it doesn't mean that you can legally settle in Spain and have permanent residency. You must go through the necessary procedures to obtain legal immigration status there.
