I am applying for a holiday visa (I was refused entry in 2018 as a non genuine visitor) and I was advised to get letters from my friends here in the US for my application. With this, I am to get a letter from my school as well. I am wondering what the purpose of doing this is and what should the letters from my friends even say? Disclosure: I do not have many close friends so I am finding this part very challenging.
The documents I was told to get: **Letters from friends, 6 months bank info, OR letter from my school (proof of enrollment)
Is any of this really necessary if I am only visiting for 2 weeks?
