I have recently sent my sponsorship application for my parents and sister (21 year of age) under family class immigrant. I have recieved an acknowledgement letter from case processing center. As we all know the process is long so in the meantime i would like to apply for a multi TRV for my parents and sister. My father is retired, my mother is a house wife and sister is a full time student. as i will be supporting their visit . Can anyone please clarify how much balance do i need in my bank statements for succefull application and what are the chances of my sister getting a visa as she is young .
Thanx.
