I just finished my studies in UK and I am going back to Malaysia to work. If you've built your career in Malaysia and you think you are capable of getting a job here due to your experiences then you can try but if you're a fresh graduate and can't prove that you're better than the british grads and Eu grads then I suggest not to risk coming here to find a job =). If you're planning to come to London to work. Think a hundred times first.
1. The competition here is high. The number of people coming in to London to work is massive. Not only Malaysians, there are plenty from Europe under European Union, Australians, South Africans, Canadians, Chinese, Malaysians, Nigerians and the list goes on. Brits will alway prioritize Brits and Europeans.
2. You will end up getting a very big pile of rejection letters
3. You will spend a lot of time here. My friends used at least a year or two to get a job here and they are First Class honours students and also engineering students. You will have to be good enough for them to apply a work permit for you.

But its different if you have a Highly Skilled Migrant Visa or Holiday Makers Visa. Holiday Makers Visa or HSMV you are entitled to work here so companies do not have to apply work permits for you. My friends applied with Student Visa so it was tougher.

I spend most of my money on fruits. Lolz. Yes transportation is very expensive. Btw Geminist I don't spend the same amount of time people spend here to get a job back in Malaysia. I've already gotten offers from Malaysia before my return. As for here, been attending UK Career and Education fair and organizations have stated clearly they will not apply work permits for non EU or non Brits. It depends on the type of positions you want and what they can offer to non EU or non Brits. Its difficult but I never said that its impossible however I'd rather be building a career back in my own country before thinking about overseas. I've had working experience here with part time jobs and I don't think that its all that great here. Just a personal opinion. I know it isn't based on your qualifications but qualifications does play a major role in whether you are worth their investment on you or not.
