Question to the Home Office:
To ask the Secretary of State for the Home Department, what the average waiting time was for a decision on visitor visa application from (a) US, (b) Russian, (c) Indian and (d) Chinese citizens in each of the last five years.
Information on performance against service standards for UKVI international operations is published in the Migration transparency data, the latest publication of which is available at: https://www.gov.uk/government/publications/international-operations-transparency-data-may-2019.
These indicate that the large majority of straightforward non-settlement visas (the large majority of which are visitor visas), 98.7%, are completed within the service standard of 15 working days.
