Do you all know what is the requirement if a Chinese citizen wishes to come to Trinidad.

They have to apply for a Trinidad and Tobago business visa with these documents:
– Completed Visa Form
– One passport size photo
– Valid Passport or Travel Document
– Valid Outward Ticket
– Sufficient funds for upkeep during stay
– Proper Local Address
– Reason for visit.
However, it seems that there is no Trinidad and Tobago Embassy or Consulate in China. You may ask them to comsult their local foreign affairs office about it.
