This is Amit Singh, indian national currently studying in canada under
study permit.

i wrote this because i couldnot find appropriate answers in form filng
guidelines or CIC websites. please experts i need your help
desperately.
i am inviting parents to visit me here for six. what kind of visa is
appropriate (single entry or multiple entry)- unless something
unexcepted happens back home, while they are here they do not need a
multiple entry, in this case will it make any difference if they check
for multiple entry?

#1. at the end of #1, it asks whether your children will accompany you
to canada or not, my question is since i am already here, will my
parents say yes or no in the box provided

#5. funds available for your stay in canada, what does it include?
does this mean that we have to add up my bank balance, their bank
balance, my scholarships (brusharies), my assistantships (some of this
money goes towards my tution, do i deduce that?)
or we have to include all our property evaluations, how much of
minimum fund (in CAD) is sufficient for their visit for 6 months?

#12 e) f) asks have you or any of your family member ever applied for
any immigration visas?
since i applied for my student visa two years back and even got denied
once before i was issued in second attempt
does this mean that they have to put X mark in both e) and f) and give
my visa application number, date applied? if it is not correct what
would be the correct way to complete #12?

thanking you in advance and highly appreciate your feedbacks and
suggestions
