Non-Imm O-A Visa: According to the Thai Consulate in NYC website, "Upon arrival, holder of this type of visa will be permitted to stay in Thailand for 1 year from the date of first entry." Does anyone know if there's a time limit from the date of their granting the Visa to the date of first entry? For example, if I received an O-A Visa today, when's the latest that I would need to travel to Thailand? 2 weeks? 1 month? 3 months? 6 months?
