So I finally gave up on the hope of getting my citizenship done within 12 months and will send out my PR renewal application today - it will expire in about 4 months. But I will have some work assignments outside Canada during upcoming months, and may happen to be outside the country when the card is ready. In the application form there's residential address and mailing address (if different from residential), so can I use my work address as mailing address, as there's someone to sign for it and keep it safe while I am away.
