But can you explain this graph number 2 here https://infogram.com/trv-approval-rates-1hzj4o9mk5qp4pw
There were tons of Nigerian people arriving in TRVs and claiming asylum therefore the approval rate decreased to decrease the chances of people using TRVs for not their intended purpose. The statistics also don’t indicate the quality of the TRV applications. Some of these applicants would be denied all over the world due to lack of savings, no or almost no travel history and poor toes to their home country.
