1) Question 11 on the application asks "What arrangements have you made to seek work upon your arrival in the UK?". What exactly are they looking for? Particularly concerning someone currently still employed in the US.
2) General question on documenting past work experience: How do you handle situations where documentation might not be available? Two examples I have are: a) A previous employer that is no longer in business; and b) Self-employed business that I closed down over 9 years ago.
I can help a bit.
1) They are looking for proof that you have researched your field in the UK job market. Can you list newspapers, web sites, agencies that have job postings in your field. Have you corresponded with anyone in the Uk who works in your field? Tell them about that. List any articles or books you have read about your field in the UK. The more info, the better. Prove to them that you know what you are getting into.
2) The man I talked to at the Home Office about my application said they are concerned mainly with the last 2 years, but try to give them anything you have from those positions. Do you have a photo taken at the defunct company? As for your own company, do you have tax records, the incorporation papers, old checks, a photo of your truck with your name on it? Anything will do, but make the last few years the focus of your documentation.
Ask away! This board this the *best* resource.
