Hi Folks,
Depending on where you're applying to - Buffalo has updated its visa-office specific guidelines, specifically regarding proof of funds.
"Provide:
• original letter(s) from your bank(s) and/or other financial institution(s) confirming
the type(s) and current balance(s) of the account(s) you hold
• copies of monthly bank statements showing deposits and withdrawals for the 6
