Can I go to the UK with a China passport and permanent residence in Sweden?

China passport holders whose nationality is China are China citizens, and China citizens can stay in China as long as they want.

However, if you stay in China for more than 2 years, that is, stay in countries and regions outside the UK for more than 2 years, the British Immigration Office has the right to revoke the visa for permanent residence. This is an immigration law, and there is nothing to be flexible about.

If you have no intention of naturalization, you can return to the UK within 2 years. However, if you intend to be naturalized, this long-term "stay abroad" will deprive you of the right to apply for naturalization.

The following is a screenshot from official website, the British Immigration Office. The first three points are suitable for China people (the latter points are for people with EU nationality), that is,

they have lived in the UK for five years;

Stay outside the UK for no more than 45 days in 5 years;

In the last whole December, I left the UK for no more than 9 days.
