Here are the entry requirements for entering United States, now thankfully Covid restrictions have eased. 

1. **Valid Passport:** All travelers, regardless of age, need a valid passport to enter the United States.

2. **Visa or Visa Waiver:** Depending on your nationality and the purpose of your visit, you might need a visa to enter the U.S. Citizens of certain countries are eligible for the Visa Waiver Program (VWP), which allows them to visit the U.S. for up to 90 days without obtaining a visa. If you're not eligible for the VWP, you'll need to apply for a visa at a U.S. embassy or consulate.

3. **ESTA (Electronic System for Travel Authorization):** If you're eligible for the Visa Waiver Program, you'll need to apply for an ESTA online before your trip. ESTA is an automated system used to determine the eligibility of visitors to travel to the United States under the VWP. Here is the website to check validity of your ESTA or to apply for a new one - https://esta.cbp.dhs.gov/

4. **Proof of Return or Onward Travel:** You might be asked to show proof of your intended departure from the United States, such as a return flight ticket.

5. **Purpose of Visit:** You might need to provide documentation related to the purpose of your visit. For example, if you're entering for tourism, you might need to show hotel reservations or an invitation from a host.

Please note that entry requirements can change, however that is how it stands at the moment. Here is the UK Gov website that outlines travel requirements - https://www.gov.uk/foreign-travel-advice/usa/entry-requirements
