I thought I had all the forms filled out before I went to submit the online visa application, but I was wrong! A small screen had popped up to give me a link to another form we needed to complete for our mail-in application. Just in case you can’t find this form or you miss this step in the process, don’t forget to include the SU07-01 form. This form is filled out by the Sponsor; though you must look carefully because the first information it asks for is the Applicant’s (USA), not the Sponsor’s (UK)!
Here is the link to the SU07-01 Form: http://www.ukba.homeoffice.gov.uk/sitecontent/applicationforms/visas/sponsorship-form.pdf
