I got pulled aside upon entry due to rentering too quickly from a weeklong holiday in Saigon. I showed proof of an onward ticket to Puerto Princessa scheduled to leave in a few days so I was told I would receive a 7-day exempt rather than 30 days. To my surprise, I noticed a 30 day stamp instead. Was he just messing with me? Does anyone know if I can stay longer now? I'd like to change my flight to leave at the end of the month instead.
