Her bank account would not be recognised in India until she went through the process of getting it transferred, thats not instant though.
Recognized? By who? Who is in charge of recognizing bank accounts?
Or do you want to say my bank account in Germany is not recognized by India, lol!!! That would mean tommorow the European Union is going to stop working since there is no branch of Erste Bank in Italy or of Banco Santander in Poland.
She just needs to have a credit/debit card attached to her account, which 101% of the people have in US, and it she can get money from every ATM in the world, she can get a bank account in India the moment she lands and a make a wire from the her US account, this is no longer the stone age she will get her money in under 24 hous.
Seriously, stop making such a big deal of a thing that can be solved in hours.
when she landed there she must have had only what she had when she was arrested in the US.
That's not how things work in deportations and do use logic for a moment, if they get you on the beach they will send you back to India in a bra and bikini?
