A deposit system for weak applications sounds nice in theory but for it to work it would indeed need to be a huge deposit. With illegal labour or illegal activities (crime) one may obtain quite some GBP. The deposit of 10.000,- GBP might be laughable to some. I wouldn't be surprised if a 100.000 GBP deposit would come closer to discouraging people with ill intentions to apply for a visa. But with such deposits of 10 to 100 GBP the ordinary visa applicant and their UK sponsor/relative may still not be able to be together. In practise such a deposit system would properly only work for a hand few of people...

Too costly, complex and ineffective. A good appeal system (fast working, easily accessed free second opinion/review by an other authority then the one that processed the orginal application) would be the way ago in my opinion but the UK's current administration seems to be aiming at the opposite and killing of this route for more and more types of visa and residence applications...

They give non EU people who are legitimately married to UK citizens a hard time just getting into the UK, but have an open door policy for any EU citizen, whether they can speak English or not, whether they have any connection to the UK or not, whether they are ex cons or not.

That is part of the terms of being part of the EU, and while we are part of the EU we have to abide by the rules unless we can get them changed, but then it is an open door policy for us Brits in all the EU/EEA countries too.

Yes, and hopefully in a couple of years the Britsh public will get a referendum on EU membersip and we will vote to leave.

Brits do have the right to an open door policy, true, and this is fine when countries all share a similar level of develoment. The problem comes when people from poor countries become economic migrants in large numbers, driving down wages and causing housing and other infrastructure issues.

Clearly there is need for cheap labour in any country, bu to have no control over it is just crazy.
