KTC does offer some Retreats that are over a weekend or so for lay practioners. Rinpoche has maintained the 3 year Retreat for those people who wish to become Ordained because of the long history in Tibet of it having been done in that way to insure that the practices and Teachings are correctly learned. Some people do choose to return to a lay life after Retreat and bring the Dharma to others in a more secular way while others go for full ordanation.
