At least when you apply for residency you know you will get it.When a Turk applies for a UK visa he pays his money and may not get the visa,however much it has cost,and when he applies again he has to pay again.When you also consider how much a Turkish person earns here,it also seems unfair.The path to a UK visa for a Turk is a minefield and many do not make it,my husband was fortunate to get his first time,but many dont.......food for thought.
