the 6 month all that crap is only when u are temporarily migrating, like as a student, to certain first world or developed countries

they don't wanna be stuck paying or supporting you or even to have to pay to deport you because they actually want to use their money for hardworking and patriotic citizens rather than foreigners from other countries that only know how to vote

If you are returning to Malaysia, no problem.

If travelling overseas, and the time to expiry is less than the max time the travel visa allows you to stay (holiday, business, study), then you need to be careful.
