Hello. Please my brother is living in Canada and would like me to come and visit him for a period of 2-3 weeks. There is a place in the application form which I'm filling on line where it asks for me to write the funds available for my stay. Is it for me to write what I actually have presently in my account or what I am able to provide that may sustain for that length of time? In any case, what may be a considerable amount for me to provide? Also, how does one fill in the space where they ask for a signature if at all your doing it on line (electronically)?
