I had 60 days visa obtained in Penang, before it ended I went to Mae Sai to cross the border and got 30 days. Can I get 30 days extension on that? We were considering flying to Pnom Penh where I can get 60 days visa and we would cross the border by land after staying in Cambodia for two weeks. My husband is from Brazil and I read that Brazilians are no longer entitled to get 90 days stamps if crossing cambodian border. Is it only while visa run so not staying in Cambodia or any land crossing is denied 90 days?
