No visa is usually required for tourism or business trips within ninety days. However, entry to the US is often denied for those entering and exiting frequently, or those staying in the US for a long time. Those traveling with a visa waiver must obtain electronic travel authorization from ESTA (excluding entry by land).

It is preferable to have a passport that is valid for at least 90 days from the date of entry.

When using the visa waiver program to travel to or through (via) the U.S. without a visa by air or sea, you must obtain travel authorization from ESTA online (not possible on your phone). Do not forget this, as you may be refused boarding onto the plane or denied entry into the U.S. if you fail to obtain travel authorization from ESTA before your trip. When you obtain ESTA authorization, it is valid for two years and you can travel to the U.S. multiple times (you do not need to renew it every time you change your schedule or visit somewhere). The final permission for entry is given by the immigration inspector at the first port of entry.
Apply for and obtain travel authorization from ESTA soon after your plans to travel to the U.S. have been fixed. (It is strongly recommended that you complete the procedure at least more than 72 hours before leaving your country). You can no longer receive instant authorization after application, so it is best to complete the process early. The application can be made by a relative, travel agency (for a fee), or other third party. You can now use the mobile app of ESTA.

Generally 2 years. However, if your passport expires before the authorization term ends, your ESTA authorization also expires. You will need to re-apply if there has been any change in your name, gender, or nationality.
