I want to go abroad, and my passport and visa are all handled in China. Do I need to go through any formalities with relevant foreign institutions when going abroad?

You must go to the immigration office in the jurisdiction where you will live.

Registered account (room card)

Then study abroad and stay.

The immigration department will give you the form and what you need ... of course, you have to ask first.

Registration requires passports, visas, housing certificates and forms.

Residence requires passport, visa, room card, housing certificate, school certificate, application form, photo 2x, tax stamp (bought by the post office) and form (for the first stay, more documents are required for the second and third stays). /kloc-please accompany your parents or school teachers below 0/8.

All documents need to be copied except the forms.

Not all countries are the same ... I want to know which country you are going to.
