Passports and Visas
Countries which are participants in USA’s Visa Waiver Program will have its citizens benefit from the fact that they will not require to have a visa for travelling as a tourist or on short business for 90 days or less provided they meet a few eligibility requirements.
This does not mean that people will be able to just show up at an airport with their hands empty and just get leave for the US. Travelers must be in possession of a valid Electronic System for Travel Authorization (ESTA). The only way one can obtain this e-pass is to apply on the official website (esta.cbp.dhs.gov/esta). Getting approval is usually pretty fast and it is recommended that you have this sorted out prior to preparing other things for you trip as without it you will be denied entry in the US.

It is generally not an obligatory thing when travelling to the US, however it is recommended that when travelling you should have the routine vaccinations kept up to date.
This should be an essential thing when traveling to the US, as the cost for medical care can be financially draining should something happen. A good thing to do is to purchase an insurance at the same time as you book the trip, this way you’ll be covered if you must cancel for whatever reason before you leave.
Monetary and Banking Tips
One thing you should start with when planning out your credit cards and your money is to announce your bank that you will be travelling to another country. Tell the banks you use a few weeks before your leave as they will consider card activity in foreign countries as potential frauds and this could get your accounts frozen.
As is the case with most developed countries, ATMs are available in most towns and cities. Just remember that there will be a foreign exchange free as well as a withdrawal fee for all your transactions. This can add up to quite a bit depending on the amount at hand so try and analyze the amount after each purchase.
To avoid this, consider changing your physical money before leaving for the US. Check out your local banks and see where is the best one you can get the most from this exchange. Avoid changing money at an airport as they will most likely have overinflated rates.
Handy phone/tablet applications
When travelling to the US you should consider downloading some map applications which will help you navigate the various cities and places you will most likely end up in. Consider getting offline applications just in case you will be stranded in a place with no mobile data available.
