What is offshore bank account? What are the benefits?
Related Question 1 - those who have HSBC premier account - that bank allows you to open premier account in other countries. Is that somehow related to this?
RQ 2 - What is this GIFT city thing? Is it some way related to offshore bank account?
RQ 3 - Does NRE / FCNR accounts opened in India be anyway related to offshore accounts?
@cardio_guy
Offshore bank accounts are accounts opened in another country that can be operated by your home country.
HSBC Premier is an account in India which allows bank account to be migrated to another country when you move there, (that is not an offshore account).
GIFT City is in Gujrat which has things more streamlined AFAIK. Not sure.
No, NRE accounts are not offshore accounts, they are opened on your citizenship in India...
