If you’ve applied for a UK student visa, there are a few ways to find out if it has been approved:

1. Visa Application Center (VAC) notifications: If you submitted your visa application through a Visa Application Center, you may receive email or SMS notifications regarding the status of your application. These notifications can inform you when your application has been received, processed, and if a decision has been made.
2. Online visa application status check: You can typically check the status of your visa application online through the official UK visa application website. You’ll need to log in to your account using the credentials you created when you submitted your application. The online portal will usually provide updates on the progress of your application and notify you when a decision has been made.
3. Passport return: If you opted for your passport to be returned to you by courier or to be collected in person, receiving your passport back with a visa vignette (sticker) inside is a clear indication that your visa application has been approved.
4. Notification letter: In some cases, you may receive a notification letter from the UK Visas and Immigration (UKVI) department confirming the decision on your visa application. This letter will provide details about whether your visa has been approved or refused, and any next steps you need to take.

If you’re unsure about the status of your visa application or haven’t received any updates, you can contact the UKVI or the Visa Application Center where you submitted your application for assistance.
