Based on US custom and border protection website "CBP now gathers travelers’ arrival/departure information automatically from their electronic travel records." .
Does this mean there is no worry about surrendering I-94 card since its electronic form?
Just trying to understand if there is anything that we need to do for temporary visitor in airport while (departure) returning back to Nepal after short visit to USA?
Do temporary visitors need to go through any type of immigration process while departure in airport?
