Can I go through the long-term residence formalities if I don't come back from traveling abroad?

If you want to stay abroad for a long time, you need a corresponding visa.

Generally speaking, there are three kinds of visas that can be used for "long-term residence" abroad:

1), study visa-you must have an admission notice from the casino school before you can apply for a student visa. Generally speaking, the time that students can live on a visa is the time needed to complete their studies.

2) Work visa-If you want to get a work visa, you must have special skills or specialties, which should be urgently needed by the other country. In this way, the other party can hire enterprises to apply to the government and apply for a "work visa" for the applicant. With a work visa, you can stay for a long time.

3) immigrant visa-if you meet the immigration conditions, you can apply for an immigrant visa. If the application is successful, you can stay for a long time.

If you enter the country with a tourist visa and don't leave the country on time according to the time you applied at that time, then this behavior is a violation of the laws and regulations of the other country. For such people, they will be blacklisted by the other country-they can't apply for studying abroad, working or emigrating in the future.
