Thanks you 2. Clear. Any idea how long it takes to obtain your UK citizenship?
I think it's only been taking 4-6 weeks or so to be processed lately, and then you have to attend the swearing-in ceremony after that... but you can attend the ceremony in the US, it doesn't have to be in the UK.
Does one need to take a test, either verbal or written or both like in the US?
Yes, you will need to pass the Life in the UK test in order to apply for citizenship.
Since 2007, the test has been required for both ILR and citizenship - but you only have to take it once, so most people will take it for ILR and then provide the certificate again for citizenship.
However, if you got your ILR years ago, then you won't have taken the test yet, so you'll need to do it before you apply for citizenship.
If a US/UK married couple want to re-locate to the US ( they've never lived there prior) and one has a wee conviction of an assault (common) on their record from their mis-spent youth--- would it prevent them from being allowed in?
Well, it won't affect the US citizen, but if the UK citizen has a conviction, they will need to declare it on the application form and provide a police certificate. There is no rehabilitation of offenders act in the US, so a conviction is never spent according to US immigration and will always have to be declared.
Whether or not it will affect the application will depend on the nature of the conviction, how long ago it was and how serious it was. It would depend whether there are ground for refusal based on that conviction or not.
I have a DUI myself (stupid mistake when I was a student) and I am now required to apply for a visa to enter the US for the rest of my life. I was very worried about being refused a visa because it happened just a few weeks before I was due to apply for a US student visa.
However, other than having a blood test done to prove I wasn't an alcoholic, it turned out not to be a problem. I was granted the student visa and since then I have also been granted 2 visitor visas for the US as well... I have entered the US 7 times on those visas since my conviction with no problems other than a few extra questions.
