However, what you will definitely need to have planned and prepared is your return ticket. Remember
ESTA authorisation is only valid
for visits of up to 90 days at a time, so you will need
to leave the U.S. before the restricted time period has elapsed, as should be shown on your ticket.
Also, your travel company or airline will likely ask you for your return ticket before boarding,
so make sure you have that prepared, as your return ticket is tangible proof that you’re not
planning to overstay the 90 day limit for ESTA holders.
There can be some serious consequences if you overstay the 90 consecutive days or if you overstay
the Visa Waiver program
annual limit - that is for more than 180 days in one year. You can be banned from entering the U.S.
for a period of up to 3 years. If you overstay for more than a year, then you can get banned from
entering the U.S. for up to 10 years. In addition to these bans, if you’re caught overstaying the
limit you will be deported from the country. So, it’s important to stay within the 90-day time limit,
especially if you plan on
applying for ESTA in the future
