I have no idea about Penang but I just did this in Savanakhet. I got back 5am this morning. The crowd on the first day was terrible but thankfully they stayed open past 11 to get everyone to hand in documents. They also opened earlier than 2pm the next day for pick up. I was very happy to get it. I didn't need any financial proof.
Excellent post. I have just had to find a new place to live after landlord decided to kick me out after requesting he notify immigration I was staying here. Wil just do it myself now. :)
