Electronic System for Travel Authorization (ESTA) is a simple and easy way to seek admission in the USA. Unlike visa, it does not require too much of documentation, or different levels of scrutiny to be cleared; neither it makes you wait for weeks for approval. It is a completely automated procedure, so you just need an internet connection to file your request.
Once issued, ESTA VISA is valid for a period of 2 years or until your passport expires; whichever comes first. It also enables multiple entries to USA for a stay of 90 days in total.
