Separated spouse
Where a spouse was not examined as part of the application for permanent residence because
the applicant and spouse were separated and examination was not required, the spouse cannot
later be sponsored as a member of the family class by virtue of their relationship to the sponsor.
This was true under R4(2) of the previous legislation and it is still valid under R117(9)(d) of the
current legislation. To preserve the option
She is not examined. There is only H&C can help and I assume the success rate of H&C is really low, right?
I assume the separation itself means you are saying they are not members of the family class. If she was examined, then you can sponsor her. If not, you are out of luck, except for possible H&C.
