I can speak only for Singapore, but banks here require very high deposits and minimum required balance if you are not a Singaporean company (at least when I asked, it was ~$50,000 - still better than UBS in Switzerland who wanted CHF 100,000 four years ago). We're one half UK resident, one half not, and the UK bank put up the fraud check, which required about 30 pages of paperwork including three different proofs of ID copied and authenticated by a notary public (cost me $30). They were and are ultra slow and do not accept any form of internet communication - only snail mail, phone and in-person counter service.
