Ok so if I understand, someone in your family works at the school and you want to join them until you can apply for MM2H and then what, they leave Malaysia after their teaching ends and you stay here in retirement, is this correct? Or, what is your plan should they leave? They dont have unlimited time here, it was 10 years max and I am not sure the current limit.
Second question is, if you dont now have the high money needed for MM2H at 67 years old, under what circumstances will you have it that dont exist now? Are you still working and saving, or would they be paying you as baby sitter and is that expected income sufficient to top-up the balance needed for MM2H? Or, are you thinking in a different direction, to simply come and live the way you are presently for the longest time possible?
As others have said, it used to be that they would let people in and out but thats mostly gone now. In a case like this, and if you are truly serious about MM2H, its better to stay out until you can apply properly, be granted the status and move here on that program.
What is gone now, and I mean nothing against you personally, is the idea that a person can come, hang-out, see how you like it, see how it goes, hang around here and Asia, maybe stay, maybe go. Today, you need a firm reason which is employment, study or marriage which falls in line with countries like US and Asia and elsewhere. And Immigration would never accept a quasi-promise of maybe applying for MM2H later as the reason to be allowed to stay now and until then. Impossible. They would tell you to apply for MM2H, and preferably from abroad. Your idea was valid and workable in 1995 but not today.
I think of the year 2000 as the good old days but really it was long before that. In 2000 I met an expat who owned an English school in KL. He came in 1976 and simply stayed. He was never questioned or harassed or anything. At some point they straight gave him permanent residence just because he was here so long. He never had a single visa run.
One might think it was easy to stay because things werent organized well. No. Malays are clever and cunning and made it easy because they wanted expertise and capital. Today, they believe they have stripped expats of whatever they could and now its out you go. Expats say, but we bring cash in! Sorry, xenophobia trumps cash unless you bring billions in and even then they still hate you. To me, its small-minded and unreasonable but thats how it is. To some degree, all expats are mistreated and disliked, visa or no visa. Even marriage, kids and a mortgage doesnt change that. Through xenophobia they derive that expats pollute and dilute the culture as well as bring virus and disease with them to destroy the population. Expats think, well I dont care about that! I want to live there! Not so fast, you need locals for cooperation and comradery or you will be miserable.
The reason for the increased difficulty in things like visa runs isnt so much because Malaysia is becoming modern and organized, its moreso because the presence of expats doesnt help the Malay-Muslim population increase and thrive. Even though I am here on a proper visa, I doubt there is an expat who keeps a lower profile than I do. I can tell on the faces of locals how they feel about me as a foreigner and unlike the old days its now uncomfortable to the point that I go out of my way to stay out of their way and thats no way to live.
Its the dream of every expat to live in a place where you are made to feel welcome to some extent and not feel you have to tread lightly just because of your origins. If Malaysia was ever such a place I feel its gone now and that should influence a persons thinking on such large life choices as moving across the world. It obviously behooves an expat to listen to those rumblings in the difficulty of visa runs and MM2H that dont come from me but the government and citizens.
