My dad went to Canada last July 2010 for my sister's wedding.
Requested for extension for 6 months and was granted. Now he went
back home here in the Philippines this month and would like to come back again soon.
1. When should he apply again for a TRV?
2. Can he go back to canada in 3 months?
3. Should he stay here for a long time before he applies again?
help!??? thanks
you can apply for a trv anytime...
my mom applied for a trv single entry last Oct 2008, and request for an extension, 4 times, which means she stayed in Canada for more that 2 years

she went home last March 2011, and a week after, applied for another TRV multiple entry, this time... and lo she was approved with multiple visa
there's no harm on trying and there's no truth that if you extend your stay in Canada, chance of getting a TRV would be very slim
to God be the glory!!!
