The term of the residence permit may vary depending on the country in which it was issued. In general, a residence permit is issued for a long period of time, which can range from several years to indefinite.
In some countries, a residence permit is issued for a certain period, after which it can be extended.
To extend a residence permit, the holder must comply with all the requirements of the migration service, such as the presence of a source of income in the country, the absence of problems with the duration of stay, etc.
In other countries, a residence permit is issued for an indefinite period, so its extension is not required. In this case, the holder of a residence permit usually has to fulfill certain conditions, such as permanent residence in the country and the absence of criminal activity, in order to maintain his resident status.
You should also consider that some countries might revoke a residence permit if its holder violates migration rules or commits crimes. Therefore, it is important to comply with all the requirements and rules related to staying in the country in order to maintain your resident status.
