Hello All,

I am applying visitor visa for my family and need your expert help.

I am applying visa with the IRCC new web based application and NOT GC KEY.

Below is the sample content when I login to my IRCC

Manage group

Start date: 2024-02-27

Days left to submit: 13

Group ID number: XXXXXXX

Group name: Family Visit

Within this one application I have added 5 applicants (Mother/Father/Brother/Sis-in-Law/Niece(6months old)) as seen below.
Please can someone suggest if I am following right way to apply visitor visa for my whole family (5 applicants).
Also wanted to know one LETTER OF INVITATION should have details of all 5 members or I have to make two Letter of Invitation. i.e. One for my (mom dad) and other for my (brother/Sis-in-law and Niece)
