My friend ""G" ran a successful newsletter biz & lived in Singapore in a rented big house for 40 years as a PT without a visa. In the old days he had to do a visa run every 2 weeks by taking a short bus ride to the border with Malaysia, having a beer & then coming right back. Now you can stay in Singapore on a tourist visa for longer and have fewer visa runs. As a "PT"or Permanent Tourist, you can live almost anywhere in the world you want to live, low profile, for as long as you want-- if you have a halfway decent passport or 2.
