invitation letter

[n_142007]

Good morning

I need help regarding invitation letter.

I want to apply for visit visa to take the PEBC exam (pharmacist licensing exam).

in my case can I APPLY without invitation letter ? is the examination fees receipt will be enough?

thanks in advance

Maybe you can write a cover letter including your purpose for visiting

also I have one friend there in Canada, is it better to relay on exam reservation only or to let him make invitation letter and add it to the examination fees receipt ?
