I know there are a lot of readers who do meditation retreats. I would highly recommend Pa Auk Tawya to readers who may be considering a retreat on the basis of my experience, though my experience is limited to the monks' wing. The center in Myanmar is certainly used to handling foreigners, and also can help with the sometimes difficult process of obtaining a meditation visa. Pa Auk apparently also has some centers outside of Myanmar, and is in the process of establishing one in Northern California. Let me give some contact information. Here are two Web addresses:
Presumably you can discover your options at one of these sites. Also I have an email address in the USA: Brian Johnson, firstname.lastname@example.org.
