Remember a visa does not entitle you to enter the United States. It simply entitles you to get on a plane. So you do not want to go upsetting the USCIS.
Um...no!
A visa entitles you to enter a country its an ESTA that allows you onto a plane/ship with a final destination in the USA - another security measure post 9/11.
You do not get a visa before you take off you get one when you land!
