Madam May, who has been living here since 2008 and runs a shop in Peninsula Plaza, is among at least three Singapore PRs from Myanmar who have had their passports invalidated by the junta, The Straits Times has learnt.
She believes she was targeted as she is a supporter of the National League for Democracy (NLD).
A general election in November 2020 saw NLD and its leader, Ms Aung San Suu Kyi, returned to power, winning 86 per cent of seats in a landslide victory.
