A temporary cap on the number of immigrants entering Britain comes into force Monday leaving some worried about a shortage of skilled workers.
The cap will affect all non-European applicants.
The scheme is a Government trial ahead of the introduction of a permanent cap next year.
Before the election, British Prime Minister David Cameron promised to cut the annual immigration numbers from the hundreds of thousands to the tens of thousands.
With the cap in place only 5,400 professionals will be able to work in Britain.
A further 18,700 workers in skilled jobs will also be allowed to work in the UK.
