The United Kingdoms immigration policy seems to be working well for them so far. I think it would be safe to say that it has protected them from having extremists enter the country and cause problems. As far as I know they have a good country and everything seems to flow well.
No, the United Kingdom's immigration policy does not work to prevent extremists from entering the country, because it has not bee effective, as there are a lot of extremists present in the country. Across the pond, we hear occasional stories about what an extremist in the United Kingdom has done or said. It is quite evident they are present in the country. This is probably due to immigration policy that liberally allows citizens to bring their relatives into the country. Their beliefs need to be vetted before this is allowed.
I believe it is important for us, as human beings, to realize that no policy will fully guarantee that extremists will be kept from entering the country. Given the amount of intelligence collected and the red tape necessary, it certainly reduces the risk, however that also makes it difficult for other people to immigrate to the United Kingdom as well, so its a double edged sword, so to speak.
The United Kingdom's immigration policy does not always work to prevent extremists from coming into the country disguised as innocent people. It is clear that there are numerous extremist in the country today, and that they are a danger to the country. The government should do more to prevent such people from entering the country.
The United Kingdom immigration system is a complicated, clunky
rattletrap. It is easy for the ill-intentioned to game, and difficult for the innocent
to fathom. The system does not protect the country from malefactors, because it
is such a bureaucratic tangle that its agents hardly know who they are
admitting to Great Britain, or why. To protect the country, this antiquated
system must be rationalized, and soon!
