Why is the UK Losing Foreign talent and by how much?

Studies published today by officials have recorded a massive drop in international students and workers who have high levels of promise and education.
This comes as a result of much more exclusive Visa laws imparted within the last few years.
The exact drop was 39%, which is a massive amount to see, and predictions toward the harm this will impart on the UK economy are negative almost unilaterally.
This news leaves many businesses angry, as they rely heavily on well qualified people of international states, leading to concern whether these tighter non EU Visa laws are actually doing more harm than good.

The students produced by these countries are very highly held by prestigious business schools across the nation, who have noticed a differentiation in attendance that they find worrying as a large percentage of their attendance is foreign.

More work and effort to apply and receive a UK Visa have made the country less advertising toward external nations, with stricter regulations and policies making it very difficult for graduates to find employment after finishing school, something that for a long time was very easy due to the high level of qualification and skill these candidates tend to own after attending the schools.

Undoubtedly, events here will have a distinct imprint upon the recovering economy of the country, a worrying prospect after a triple dip recession, that we are now, while in recovery – losing potential moneymakers.
Furthermore, these transfers were good for international relations, as the newly qualified students would go on to work for sometimes massive international companies which would provide income to a large selection of nations.

The effect of talented foreigners leaving the UK

Many modern technology companies rely heavily on qualified international students which have graduated from the UK businesses schools to provide valuable services in many sectors.

This heavy hitting loss in the stream of these individuals could stress the companies who are involved as much as it is damaging the UK.
However, recent news of more streamlined Visa processing services, starting with China, may provide a way out for this downward spiral which we face although, damages has already been done toward the economy, leaving a bitter taste in many high level employers of profitable industries.
Commentaries on the issue highlight the general consensus within the business community that they are now losing a lot of potential along with many already highly talented workers that could be contributing heavily to the nation and international horizon.

Who is responsible?

The government imparted these harsher Visa policies in an effort to curb indecent behaviour and large losses that are accounted toward some immigrants.
Some may argue that the situation is unfair on those who had huge potential to succeed in the UK that have been undeservedly rejected by the border agencies.
However, others argue that this is part of the process which is still very flawed as it involves many new polices that were put forward within the last couple of years.
The situation presents many moral questions.

Is it fair to bias toward talented, qualified individuals in the immigration sector?
