If you are currently in the UK on a student visa and want to apply for a new visa, you can choose to cancel your current visa and apply for a new one. However, it is important to consider the implications and requirements before making a decision.
To cancel your current student visa, you can contact the Home Office or UK Visas and Immigration (UKVI) and inform them of your intention to cancel. You may need to provide relevant documents and information to support your request.
After canceling your current visa, you can then proceed to apply for a new visa. The process will depend on the type of visa you are applying for. You will need to meet the specific requirements for the new visa category, including providing the necessary documents and meeting the financial and language proficiency requirements.
It is recommended to seek advice from an immigration lawyer or an authorized immigration advisor, as they can provide accurate guidance based on your individual circumstances. They can also help ensure that you meet all the requirements and submit a strong application for your new visa.
