Hasina will stay in India for the time being, but without refugee status, know why there is no refugee policy in the country which gives shelter to millions of people?

Bangladesh is currently going through a period of instability. Former PM Sheikh Hasina, who was removed from power, left the country and came to India in view of security. He is here since 5th August. But this arrangement is temporary. In fact, due to not signing the Refugee Convention, India has no formal refugee policy.
