Is it better not to mention that I have relatives in the UK during visa application to avoid migration suspicion?

No, you should always answer honestly on your UK visa application. Not mentioning relatives in the UK when asked can create suspicion if this is discovered later, which may harm your visa chances.

Having relatives in the UK is common and does not automatically create migration concerns. The key is to clearly show your genuine intent to study and your strong ties to India. If you need help presenting your case, your Leap counsellor can guide you.
