Are there assistantship opportunities like teaching or research assistantships available in US or UK universities for international students for a PhD/Master's?

Yes, assistantship opportunities - such as teaching and research assistantships - are available to international students in both the US and UK, but their availability and structure differ.

- US: Assistantships are common for graduate students, including internationals. They often provide a stipend, tuition waiver, and sometimes health insurance, but are more widely available at the PhD level than for master’s students. Selection is competitive and usually based on your academic profile and department needs.

- UK: Assistantships are less common at the master’s level and are mostly offered for PhD or research-intensive programs. Some universities offer paid teaching or research roles, but these are limited and highly competitive.

Visa rules and eligibility requirements - such as English proficiency for teaching - apply and are subject to change.
