Can I change my son from West Bengal Board to CBSE Board for 11th & 12th?

Ans: Hi, I understand that you pursued a medicine course in Russia (a non-European country) and, since you are from India, you have completed the FMGE. Now you want to practice or work in the UK as a doctor?

Based on your question, you are eligible to practice in India after completing your internship (which you haven't mentioned, but I assume you have completed it). The FMGE is essentially a licensure exam for Indian students who have completed their medical studies abroad, so you are eligible to practice in India only.

If you want to practice medicine in the UK, you need to complete the PLAB test, as you are from outside the UK/Switzerland/European countries (Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland).

You also inquired about sponsorship. Here is the information related to sponsorship for practicing medicine in the UK.
(Extracted from general medical council, uk org. )Applying for registration using sponsorship
If you apply through sponsorship, you will have to satisfy the sponsor that you possess the knowledge, skills and experience required for practising as a fully registered medical practitioner in the UK. Each sponsor has their own scheme which we have pre-approved. If you can satisfy the requirements of their scheme, they will issue you with a Sponsorship Registration Certificate (SRC) which you will need for your application with us. Please ensure this is a Sponsorship Registration Certificate for GMC registration, as we can’t accept UK visa sponsorship certificates for your application for registration.
Please note that a core part of all sponsors' criteria is that a doctor applying for an offer of sponsorship must have been engaged in medical practice for three out of the last five years including the most recent 12 months. If you cannot meet these minimum criteria, it is unlikely that you'll be able to supply sufficient evidence to support your application for sponsorship.
Doctors applying through sponsorship are required to demonstrate their English language skills by achieving our current minimum scores in the academic version of the IELTS test or the OET (medicine version).
