At the age of 50, can I still apply for a foreign university?

1, yes. You can also apply for foreign universities when you are 50 years old.

You can definitely apply for studying abroad as long as your foreign language scores and academic qualifications meet the requirements of the school you are applying for.

There is no age limit for applying for a university abroad: as long as you meet the application conditions of the school and are admitted, you can go abroad to study at the university, and you must obtain a visa from the embassy or consulate of the applicant country.
