What can I do?

This is the first time that I managed to pass an interview after 2 failures, however before allowing me to proceed to the next stage, I am told that the company doesn't employ people who need work permits...
Oh well..what can I do? I am starting to feel numb about job applications. KPMG cancelled my interview the last minute ?? They have made offers to people already..but I got my interview booked a month earlier before the cancellation... surely they should interview people whom they have invited first before making any decisions... AGAIN..what can I do?
Its really hard getting a job in the UK ..the recruitment process is so long and nerve-wrecking.. It drains one's brain and mind mentally and emotionally...Cheers to those who manage to pass all the stages...Each company will have an average of 3/4 stages... haih....
I hope to get a job here..after all I need to qualify as an actuary but it's really hard to qualify in Malaysia and with the menial wages...how can you pay for your exams? Plus, all actuarial students pay so much to get a degree ... and after that it's as if that you haven't gained anything from it...
What can I do? Persevere??be optimistic??Let it be??

God shall decide
