What are the visa implications or differences between these master's degree types in UK/Ireland?

It depends on the country, but generally, visa rules and post-study work (PSW) options are similar for taught, research, and professional master's degrees in the UK, Ireland, and the Netherlands.

- UK: All master's types usually qualify for a Student visa. After graduation, you can apply for the Graduate visa (PSW), currently allowing up to 2 years of work (reducing to 18 months from January 2027). This 2-year period applies to applications made before 1 January 2027; applications submitted on or after that date receive 18 months, while PhD graduates continue to receive 3 years. Research master's may offer slightly more flexibility for dependents.
- Ireland: All master's types require a student visa. Graduates can apply for the Third Level Graduate Scheme, which allows up to 24 months of post-study work.
- Netherlands: All master's types require a residence permit. Graduates are eligible for a 1-year orientation year permit to seek work.

Visa rules and PSW durations are subject to change and may depend on program accreditation and duration.
