Hi,
Here are my suggestions:
Financial Situation
6 month bank statement with 1600 CAD
CAD 1600 in the bank account + CAD 2000 as cash is less.... as an unofficial guide, the applicant must show about CAD 1000 per week of visit + airfare + money for other incidentals
You/an immediate family member can provide a Letter of Financial Support.... to help your mom with some of the finances for her visit.... is this is a possibility? Did the Invitation Letter from your brother state that he will take care of your mom's accommodation/travel and living expenses during her visit?
Your mom must also submit Interest Certificates from the banks where she holds the FDs + show the interest is deposited in her bank account (this may not apply to FDs that earn cumulative interest) + a letter from each bank stating the FDs are not locked-in/not mortgaged.... and can be liquidated, if required.
CA certificate mentioning above all assests plus 2000 CAD cash in hand...jewellery worth CAD 6000
Any evaluation by a CA must also have supporting documents
Does your mom also have Gratuity and PPF (which she can withdraw)..... or EPF?
Did she submit proofs that she earns a pension? And any other benefits that she is entitled to?
Does she have any other financial investments? LIC?
You may also want to prepare an Explanation XX: My Financial Situation.... in this you can list all liquid cash + locked-in finances (for example, jewelry will not help to fund any component of her visit)
Her Strong Ties to India
Property Ties
Property evaluation certificate approx 100000 CAD
Does she own the property?
Did you also submit copies of the Sale Agreement + Property Tax receipts + does she live in the property or is it rented out?
You must also submit supporting documents to confirm the market value as assessed by the CA
Does she also own any land? Either sole ownership or joint ownership?
Family Ties
Does your mom live alone or with other immediate family?
Other Ties
Does your mom volunteer or do any social service?
What other ties can your mom show to India?
What did your mom give as Purpose of Visit?
Cheers
