Apart from the POA my builder is also asking me to furnish a certificate from the bank approving my photo, signature and address. Is this a regular procedure? If yes, will my bank in US provide such a certificate?
Not sure about this kind of certificate. What you can do just write all the details on a piece of paper with your photo and get it attested by your bank. They will attest it.
I have never heard about this kind of certificate.
