My daughter is a South African national and flew with BA via London to the USA. She did not need a transit visa (DATV) due to holding a valid USA J1 visa for this trip.
Her J1 visa expires on 30 Nov, BUT she is validly staying on in the USA until 29 Dec on the 30-day Grace Period allowed by the USA for J1 visas – so she is technically still validly in the USA until 30 Dec.
Her BA return flight via London is on 29/30 Dec and we did not get a DATV for this either as we thought that (as per Section 2.6 of the GOV.UK document under exemptions) as she is now on a valid return trip via the UK less than 6 months since she entered the USA with a valid visa, that she did not need one.
Is anyone able to confirm what the correct status is regarding a DATV for her return trip. She is now obviously already in the USA so can she apply for a UK transit visa whilst in the USA (not her country of permanent residence)?
MANY thanks for any advice.
