PSW stands for "Post-Study Work" visa, which is officially known as the Graduate Route in the UK. It allows international graduates to apply for a visa to stay in the UK for a fixed period of either two or three years after the completion of their degree studies, depending on their level of study. The PSW visa provides a more straightforward way to stay in the UK lawfully after graduating compared to other visa routes. To be eligible for the PSW visa, you must have completed an undergraduate degree, a Masters degree, or a PhD from a qualifying institution approved by the UK Home Office. The PSW visa application fee is £715, and you will also have to pay the Immigration Health Surcharge for each year of your leave. The ideal time to apply for a PSW visa is before the expiry of your student visa in the UK.
