Old passport required for Visit visa?

[AshyS]

Dears,

My parents are planning to apply for temperory visit visa. However, they do not have their previous passports with them. Their current passports were issued in 2015. Are old passports/digital copies required for applying visit visa?

Thanks!
Ashy
