Dear Massood,

First of all thanks for your efforts in answering all the questions of the people.
I never forget your advice, which you gave me last year for my immigration ( PR ) to Canada.
I got my PR and I am successfully settled in Canada.
Again, I came for your help.
My parents are planning to visit me along with my younger brother.
My father is central govt emply and mom is house wife and my younger brother is abt to complete his engineering and he already got the job in IT , got the job through campus interview and he may join the job in another 4 -5 months. Before to that he wants to visit Canada.
My another younger brother is in USA and he is on H1B Visa status and he visited me last month and he got the Canada visit visa.
I have already sent required documents to my parents.
I have few doubts abt the application forms.
What are the documents should my parents submit to CHC.
IMM5257B
PIF
Consent
TRV_Checklist
Is these four forms are enough or they should send any other applications forms.
In the form IMM5257B, only my father has to sign the form or all the three people has to sign the application form.
Only one IMM5257B is required or three separate forms required.

Please advice me

Thanks in advance
Goud
