ksand24, from your advice I have drafted the following sponsorship letter. I didn't want to include lots of redundant info...based on your experience would you consider this suitable, or should I include more? Do you think an inventory of all the included documentation is important on this letter or just let them work through it (as they will anyway)?
To whom it may concern,
Regarding:
<wife's name>, DOB: <date>, Nationality: United States of America
<daughter's name>, DOB: <date>, Nationality: United States of America
<son's name>, DOB: <date>, Nationality: United States of America
I am writing to confirm sponsorship for my wife, <name>, and our two children, <name> and <name>. As a British citizen, I will be settling in the UK and wish for them to join me. (I wasn't sure about this sentence...not quite sure how to word it?)
<name> and I met in 1993 while we were both still in high school. We began dating shortly thereafter and were married in January, 1999. Since that time, we have lived together in a committed relationship to one another, and as devoted parents to <name> and <name>.
I have worked for 20 years as a technology professional and I am currently employed by <current employer>, a management consulting and technology services firm. My gross salary with <current employer> is $<salary>/year (approximately £<salary>). I have a confirmed job offer in the UK beginning 1/1/2017 with <new employer>, and my gross salary will be approximately £<salary>/year. Because I am currently employed overseas and have been with <current employer> for slightly less than 6 months, we are applying under 3B, Category B.
I accept all responsibility to maintain, financially support, and accommodate <wife>, <daughter>, and <son> in the UK.
Upon arrival, we will temporarily stay with family located in the <city> area, and immediately begin the search for our own home. We plan to live in <city>.
If you should require any further information or clarification, please contact me:

Sincerely,
<full name>: <signature> <date>
