Itโs gonna be very difficult battle for you. You will need to get an human egg first. Surrogacy process is expensive but still straight forward in foreign country. But the egg donation part raise ethical question. Many women donโt want that even for fuck you money. I know I will never give my egg to anyone. Like ever. This is gonna be difficult.
Then comes the next step. You will have to apply for citizenship in India for the kid. But the kid is not purely Indian. Gov will find out itโs a foreign egg. Gov has already banned egg donation for Indian women. I am not sure how tolerant laws are for foreign import.
The reason why itโs possible for married couple to have surrogacy is because the wife actually donate the egg. For you, thatโs not an option.
