Your suggestion is helpful. Thank you Scylla. I also search some legal cases till now I do not see a case rejected just because the reason of not including their spouse. But there are tons of cases there so I am not sure...This doesn't really make sense to me to be honest. But I'm not IRCC.
If this is really honestly the reason why she was listed as non-accompanying, then provide that reason.
If the real reason is because you needed more points, I would be honest and say that.
Just my two cents. I'm not a lawyer.
Does anyone here know a case rejected by the reason for not including their spouse?
