how i know that??they also issued me R-1 in visa ,but what am sure,that i provided them why it was impossible to meet the obligatory period?
R-1 coding means you were found in compliance with the RO.
RC-1 coding means you were not in compliance with RO, but had acceptable H&C reasons to overcome it.
Seems an error was made in your PRTD visa coding, since obviously you weren't in compliance with RO. Same situation has happened to many other people on this forum. A few have reported they applied to renew PR card immediately and were successful.
So safest option is to wait in Canada 2 years. However you could also try to renew immediately since PR TD was very recently approved. Up to you which way to proceed.
