Visitors Visa-Documents

[immihelp]

I would like to invite my cousin and his wife and 3 children who live in Canada to visit me in March for one week to attend my brother's wedding.

The guidelines online states bank statements and 3 years of tax returns. It seems much for one week of visit. Can you tell me the maximum documents I need to provide as the sponsor? Thank you in advance for your answer.

The documents we have listed are the recommended documents for sponsoring visitors visa.

It is up to you to provide whatever documents you feel are enough for it.
The consular officer is free to make whatever decision they want based on it.
