My son is a Malaysian passport holder residing in Chennai,India.About a month ago he had gone to visit his sick grandfather in Malaysia.We as a family are planning our yearly trip and this year planned our trip to Toronto.My husband (indian passport)and i (Malaysian passport)already have our Temporary tourist visas.Since my son was in Malaysia he decided to apply for a temporary residence visa to Canada.His biometric took place in Singapore and after one month, today he was asked to submit his passport.He however returned to Chennai a few days ago because he has to travel to US under B1/2 visa for a semester programme tomorrow.I need to know if he can submit his passport with the relevant receipts to a VAC in LA.An appropriate reply is greatly appreciated.Thank you.
