The first three bullets above will almost certainly prevent you from obtaining authorization to go to the United States, but in many circumstances, the refusal is due to you answering “yes” to the health or criminal history inquiries.
The health concerns are about communicable endemic diseases like Aids, not a cold or anything more catastrophic like pneumonia. The question concerning “severe offences” is another that is frequently answered “yes” when it should be “no.”
Serious crimes against people or property are more than just assault, drunk driving, accidents, traffic infractions, and a slew of other offences.

You may avoid the most frequent mistakes and acquire your travel permission fast if you are diligent and take your time filling out your application.
The ESTA approval authorises you to board a mode of transportation bound for the United States. One of the most significant changes made by the ESTA is that if you have a stopover in Canada, Mexico, or Central or South America, you must obtain an ESTA permission.
For others, this has been a major source of disagreement since they believe that if they are flying to Brazil and have to stop in Los Angeles to meet a connecting aircraft, they should not have to go through the system to obtain an ESTA permit.
While it is accepted that it is an additional step, and it may appear to be an unnecessary step if you are never leaving the airport, bear in mind that the additional step is for the security of all travelers, not just Americans.
Everyone has the right to arrive at their destination safely, and this tiny extra precaution may go a long way toward ensuring your safety.
Once approved, your permit is good for up to two years. In other words, if you have business to attend to, you can go back and forth for two years on the same approval. You can use the clearance for two years as long as each trip is no more than 90 days.
