- Thailand: Foreign travellers must submit the TDAC within 3 days before they arrive in Thailand. Cambodia: You must complete and submit an e-Arrival Card within seven days prior to your arrival. Vietnam: Travellers can submit declarations within three days prior to their entry into Vietnam, or upon arrival.
