We made cover letters too and these are dated Jan 31 Is that okay?
For the letters, a letter from the sponsor in support of the application is mandatory, but a letter from the applicant is only optional and should only be a contents letter for the documents.
The sponsor letter should include:
Paragraph 1: how you qualify to be a sponsor (your UK citizenship)
Paragraph 2: your employment details and which financial category you are applying under
Paragraph 3: where you will live together in the UK, including full address and property details
Paragraph 4: short, factual history of the relationships (dates and locations only), plus the reasons why you are choosing to settle in the UK together and not the US
The applicant letter, if you choose to include one, should just really be a contents letter for the application documents, plus an explanation for anything unusual or complicated about the application.
For example, an explanation for:
- anything unusual about the documents you are including (i.e. large bank statement transactions, or reasons why you cannot provide a particular document)
- any previous refused visas or entries to the UK
- any previous illegal working or overstaying in the UK
- any criminal convictions the applicant has
