What is the total duration including study and work experience to qualify for PR in the UK for a Master's?

After your master's, you can stay in the UK for two years on a Graduate Visa, but only time spent on a Skilled Worker Visa counts toward permanent residency. Usually, you'll need to work in the UK for five years on that visa, so the total duration is about seven years including study and work. Please check for updates, as policies may change.
