If your brother's situation was the same in 2010 i.e. he was taking care of the agricultural land for you/your dad/your relative + he retained all the income earned from it then you may want to order GCMS notes for his 2010 TRV refusal. The notes may explain the refusal on financial grounds.Ok, got it. Thanks for the advice.
If he applies, he would want to prove at least 2-3 compelling reasons to return to India (not just his children who would be cared for by the maternal grandmom) because his family ties to Canada are stronger if his wife also applies
