Can I extend my Non-ED visa by 30 days with an embassy letter after cancellation?

The conversation discusses the possibility of obtaining a 30-day extension through an embassy letter after cancelling a Non-ED visa. It highlights that many have successfully secured this extension, but emphasizes that letting an extension run out differs from actively cancelling it. Importantly, obtaining a letter from the educational institution is necessary to facilitate the process, and one should consult with the local immigration office for specific requirements.
