@audreamer05 from the question na "Have any of the applicants lived in a country other than the PRIMARY APPLICANT'S usual country of residence?" sa pagkaka intindi ko dito is:
Other countries you had lived with besides your nationality country (Philippines)
Other countries you had lived with besides your current country of residence (Singapore)
If single applicant ka eh ikaw rin ang primary applicant ang sagot dyan is "NO"
If you have dependents na kasama sa application mo they are considered applicants also or secondary applicants then ang sagot mo dyan ay "YES"
Example: If your wife or husband used to work or currently working in Middle East, States, or etc countries or if your sons or daughters used to study or currently studying in other countries than the Primary applicant's (YOU) usual country of residence na di mo sila kasama is need mo i-state iyon.
