Yes we can, but it is much easier to open a corporation and bank account in Panama.  We can form the corporation and open the bank account in about 3-5 days.  We cannot guarantee the success of opening a bank account with your existing corporation because the bank does not know your directors.  If they insist on doing due diligence on your existing directors it may get expensive.  For this reason we recommend that you open a Panama company with a similar name.

Also banking privacy is severely compromised when a Panama bank account is owned by a foreign corporation, where the banking privacy laws are not as strict.  (or strictly enforced)
