A mini advice from Penang.
If you are going to Consulate by yourself for your any kind of visa, a tiny bit of tip here.
Dress properly. Especially when you apply Non-O/B/ED visa.
For ladies, cover your skin as much as possible - shirt with sleeve, long sleeves if possible. Not too short hot-pants style for bottoms. Wear shoes, if not, proper sandals not beach sandals style flip flops.
For gents, ware shirt with sleeves, not tank top. With collar would be better. Long pants, and if half pants, try as long as possible. Wear shoes. If not, no beach sandals, maybe sports sandals at least.
Not backpacker-ish style for Non-immigrant visa.
These are advice from the agent in Penang, who is visiting consulate for customers' visa everyday.
Malaysia is one of Muslim country, though you don’t have to wear like them. But the agent said Muslim staffs wouldn’t appreciate too-much-skin-exposure dress. Thus appropriate dress would help especially when your application is not super-perfect. Even the papers are okay, if some officer sees you don’t dress appropriate, they might try to find the reason to reject your application.
This is what one of the agent said and he also said he saw many were rejected.
I’m not sure how much this would help. Or maybe not at all. But this is what I got in Penang for Thai visa.
