I just received my In-Principle Approval for my LTVP application and have 30 days to submit the documents requested (medical check and marriage preparation program).
However, my STVP expires in 3 days and I just applied to have it extended, but it was rejected? I'm very confused by this. The LTVP approval email said that "This notice does not constitute a valid pass to remain in Singapore. It is the responsibility of the applicant to ensure that he/she has a valid immigration pass to remain in Singapore at all times. The applicant may seek Visit Pass extension online (https://eservices.ica.gov.sg/esvclandingpage/extend).
