Yes sure as suggested by you, I will definitely carry the bank statements but I assume that visa cards for international banks e.g. HSBC we can use worldwide.istari said:I doubt it. How would that even work ? Showing that you have a debit card gives the VO no information other than that you have a debit card; he doesn't know how much money is on the card.
You need a bank statement.
I am being precautionary if VO asks okay here is your statements which says you have enough money but how you gonna make use of it in case you need more than what are you carrying as cash?
Then I can say I can always use Debit and credit cards although it will charge me for overseas TX's.
