Question to the Home Office:
To ask the Secretary of State for the Home Department, what restrictions apply to Iranian citizens applying for tourists' visas to visit the UK.
There is no current policy of restricting applications from Iranian citizens looking to visit the UK on a tourist visa.
The rules applying to visitors can be found on GOV.UK: https://www.gov.uk/guidance/immigration-rules/immigration-rules-appendix-v-visitor and apply to both Visa Nationals including citizens of Iran (who must apply for a visa in advance of travel) and Non-Visa Nationals (who seek leave to enter at the UK border).
