Banks require a lot of paperwork, nearly perfect credit and for you to be able to put up some money. It usually takes a month for them to Approve or Decline your application (banks have high decline rate) Even if you do get approved for the working capital now you have to wait a few months to even get the money in your account.
International Banks.... hmmm very skeptical because they're are more scammers than real lenders. I've tried international loan but almost got ripped off for $18,000 of my own money, luckily I have a friend that helped me.
I hope that helped you.
