My work permit will be expired in May 31, and I will leave Canada then. But I am planning to return Canada in this Summer as a visitor. Can I apply for a new temporary resident visa from within Canada NOW? Somebody told me that if I apply for a TRV now when I am still in Canada, the new TRV's period will be the same with my work permit, that is May 31. Could it be a new TRV with 10 years period, so that I can use it in this Summer?
