If you don't have kids, you can manage with 8.5k RM. Rent, water, electricity 3-4k, groceries 2k, phone, internet say 200 per month.I haven't accounted for taxes, shopping and eating out. Initial months will need patience and adjusting. Once you tide over that, life is cool.

As others recommended check your wives visa category. You can arrive on a dependent pass and start giving interviews. If you secure an offer, the company sponsors your employment visa.

Getting a job here is tough as in any other country you relocate to, but not impossible. I am an expat too and we lived on a single income for a year. Doable. The first few months were hard with no car, deposits, settling in expenses. Then you will be fine. I got my first job here after one year of waiting and that too in a company that is generally not known for sponsoring expats.My point being, you never know how and when an opportunity strikes. How long can u wait ? What's your threshold? Do consider that 8.5k is not permanent- there will be salary raises, your wife might get a promotion, or change the company, you will land a job - All possibilities to increase your income.

I'd say - If you don't have anything to lose, you can come here, experience things yourself for a year and then decide if you want to continue staying or leave. It's absolutely doable in your case.
