Hello!

I'm getting ready to send off my application to my courier in l.a. I was advised to write a cover letter in support of myself, however i've been told by other sources that it wasn't necessary. Has anyone had issues or been refused because they did not supply a letter? My husband wrote a support letter but is that enough? If the letter is not needed, i rather spend my time trying to de-stress myself from all that is uk immigration, just for a little bit. so any advice or experience is more than welcomed! Thanks!
