Maybe it would be nice (I realise I am dreaming) if those people from places like the USA are given more of a break on the regulations. somehow.
Americans have a lot to be thankful for!
The USA is a fast-track country, and that's as easy as it gets. DNA testing is unheard of. TB & HIV exams are non-existent. No one here has ever reported a T4 settlement interview, most wouldn't know what it is. As a matter of policy, ECOs on the North American desk are told not to use the discrepancy method where it is encouraged in Africa and Asia. No one here has ever been refused a settlement visa; they approve fiance visas that wouldn't even get through pre-sift in other countries.
The North American consulates use the Doctrine of Comity with American divorce certificates, university transcripts, and birth certificates. And while they have made American spouses go back to the USA get properly documented, families are apart for a matter of weeks, rather than YEARS.
Oh. When did anybody last hear of a house inspection for a UK/US couple? As to abuse of public funds being improbable for Americans? Well, not really.
As visitors, Americans come and go largely at will, the only people with less restrictions are EU and Commonwealth cits. As visitors, we are the 2nd largest abuser country in Australia, and in the top 10 of abusers here. The Brits are a lot more patient and indulgent with us than we really deserve.
So on balance, 'merkins have it pretty good.
