Yeah. We showed property, bank accounts, fixed deposit, and some sort of business as well
It would seem rather unconvincing if someone wants to visit for just a couple of days especially if s/he is spending considerable money for that visit.
1. What exactly did she state as the purpose of her visit?
2. Did you mention anything about your mom visiting to see a newborn grandchild or pregnant daughter or taking care of a grandchild while you work? Anything along those lines?
3. Does your mom have dependent family in her home country?
4. Does she legally own the property? Or is it owned by family members?
5. There's no 'some sort of business'. Any business requires registering the business + paying taxes + proof that it is actively trading. Did she include this evidence?
