A site with lots of good info. http://www.panamalaw.org/ US CITIZENS BEWARE: you must always report and pay taxes on any structure or bank account you own worldwide to the IRS. EVERYONE BEWARE: this site has good info, but I have no good or bad references about their services. Most of that info is true but some of it is also misleading. For example, the passport offer is potentially misleading because you get a Panama non-citizen passport which is not accepted anymore in most countries, but it's useful to enter Panama without having your own passport stamped. They seem good to open bank accounts though.
