The UK has a world-leading education sector and welcomes International students for higher education every year. Thousands of Indian students are studying in the UK.
The Graduate route provides an opportunity for international students who have been awarded their degree to stay in the UK or look for work at any skill level for two years and three years for doctoral students. The Graduate route is unsponsored, meaning you do not need a job offer to apply. You will be able to work flexibly, switch jobs and develop your career in the UK.
To apply, the Student needs to complete a degree at undergraduate level or above (or one of the limited number of professional qualifications at degree level or above) at a Higher Education Provider with a track record of compliance and who has a valid Tier 4 or Student visa at the time of application. Students must complete the entire course in the UK, apart from permitted study abroad programmes.
You must have completed the qualification named on the Confirmation of Acceptance for Studies (CAS) associated with your Student (or Tier 4) visa or following a change of course allowed without applying for further permission.
To apply for the Graduate route, you need to pay the relevant visa fees and the Immigration Health Surcharge as part of your application. IHS gives you access to the UK's National Health Service. Dependants will also be required to pay the application and Immigration Health Surcharge.
You must be in the UK when you apply. It would be best if you did not leave the UK while waiting for a decision on your application. Doing so may affect your eligibility for the Graduate route and result in your inability to re-enter the UK.
The process will be digital for most applicants, and if your application is successful, you will be issued an eVisa. You will start your application at GOV.UK website, where you will create a UK Visas and Immigration account and use the 'UK Immigration ID Check' app to verify your identity. You will need your Biometric Residence Card or Permit (BRC/P)
You will need the Confirmation of Acceptance for Studies (CAS) number from your current Student (or Tier 4) visa to apply under this route so make sure you have this to hand. If you do not know your CAS number, contact your university.
The processing times for applications vary depending on how you applied. If you prove your identity using the app, the processing time starts when your documents are uploaded. If you attend a UKVCAS centre, the processing time begins after you have attended. Most people receive a decision within 8 weeks.
Suppose you have applied using the digital route; as soon as you get notification of the decision on your Graduate route application. In that case, you can view your immigration status digitally (eVisa) and prove your rights in the UK.
Under the Graduate route, you are allowed to take up additional study, but you cannot study with a student sponsor on a course which would meet the requirements of a Student visa. You are not allowed to bring new dependants, but dependants already in the UK can apply.
The Graduate route is non-extendable and does not count towards settlement. However, if you find suitable employment, you can switch to various work routes from the Graduate route.
