Sponsorship Undertaking asks if you've been charged with a crime.truesmile said:I agree 100%. If he is in Canada, he is absolutely "innocent" UNTIL proven guilty. Worry about your decision to inform CIC if and WHEN that happens (found guilty I mean) ... until then, it's a non-issue.
In Sponsor Eligibility Assesment, question #18. http://www.cic.gc.ca/english/pdf/kits/forms/IMM1344E.pdf (It's on page 2.)
Techincally if he has been charged with a crime that could net him more than 10 years in jail, he must notify CIC. OP hasn't given us an official charge and I'm not familiar enough with Canadian law to know the jail terms, but I don't think most assault charges would fit this bill.... but I don't know for sure.
The sponsor needs to determine if his crime is punishable by 10 years or more in jail. If so, he needs to notify CIC. If he does not, it's misrepresentation.
If his offense isn't punishable by 10 years in prison or more, there is no need to worry.
