Getting an F1visa and I20 can be challenging because many
governments are worried about the number of people who use these as
a way to enter their country and overstay. You will be writing a
letter to an Embassy to grant permission to study abroad for the
long term. The aim of your letter would be to show the consular
officer who considers the visa application that the person has a
specific plan, a place to stay, and will not need to find work in
order to support him- or herself while here (if that is, you plan
to offer financial backup or support).
