My in laws over 60 years of age will be applying for citizenship next year in Jan. The process is 12 month so they want to go back home for a year, i understand that as per CIC website ( http://www.cic.gc.ca/english/helpcentre/answer.asp?qnum=911&top=5 ) you can leave but just wondering since they dont have to write a test can they stay out of Canada for that long?
