Proof of Immunity for Travel to the USA - Everything You Need to Know

Many people can test positive for Covid-19 for up to 3 months, even though they have fully recovered. You can travel from the UK to the USA using a Covid Recovery Letter as your Documentation of Recovery and Proof of Immunity.

    How to Travel from the UK to the USA despite a positive Covid Test

    To travel to the US, The Centre for Disease Control (CDC) requires a positive Covid-19 test and "Documentation of Recovery" from Covid-19. This Documentation of Recovery, or "Proof of Immunity", states that you have had Covid-19 and have recovered, and therefore are likely to have natural immunity from Covid-19. Please note you will still need to be Fully Vaccinated against Covid-19 in order to enter the USA. Unvaccinated and Partially Vaccinated travellers cannot enter with Documentation of Recovery on its own.


    If you have recovered from Covid-19 in the last 90 Days and are aged 5 and over, you are eligible for a Covid Recovery Certificate for Travel to the USA.

    What You'll Need

    You will need to show us either a PDF, screenshot or photo of your positive Covid test result certificate which clearly states the date of the positive test result. (Photos of the tests themselves are not accepted - it must be a photo of official test result paperwork).


    The Covid Recovery Certificate replaces the need to show a negative Covid test, so you don't have to stress about calculating which day you have to take your PCR test before your flight to the US. Fill out the form now and receive your certificate within 24 hours.

    See an example Covid Recovery Certificate below.

    How It Works

    Proof of positive test

    Send us proof of your positive Covid test result. This can be in the form of a PDF, screenshot or photo. The proof of the positive test must show the date of the positive test result, and it must be within the last 90 days (but not the last 10 days).

    Submit a form

    All it takes to get your Covid Recovery Certificate for the US is a simple form submission that takes 5 minutes. No appointment is needed.

    Get your certificate

    Once submitted, one of our doctors will review your form. If all the information is satisfactory based on the eligibility, we will send you a Covid Recovery Certificate by email so you can travel to the US.


    Does the USA accept Covid Recovery Certificates?

    Yes. The USA accepts Covid Recovery Certificates for those who have recovered from Covid-19 but continue to test positive.

    Who can get documentation of recovery from Covid-19 for travel to the US?

    Anyone who has a positive PCR or Rapid Antigen/Lateral flow test dated within 90 days of travel and has recovered from Covid-19.

    What language will my certificate be in?

    Currently, we only write certificates in English as all airlines and border authorities usually accept English and the local language. We will require your Covid-19 test to be in English too. Currently, we only offer customer support in English.

    What do I need to do to get a documentation of recovery?

    You only need to answer our online form to assess your recovery and upload a copy of your positive PCR or Rapid Antigen Test Certificate (dated in the last 11 to 90 days). You will need to know your passport number too. We will then send you your Covid Recovery Certificate to present with your test result.

    How do I use my Covid Recovery Certificate to travel to the United States?

    You will need to present your Covid Recovery Certificate alongside your positive test result. You will still need to show proof of vaccination as well, such as your EU Digital Covid Certificate or NHS Covid Pass. On 24 January 2022 the CDC requirements were that the test needs to be within 90 days of travelling, and you need to have completed 10 days of isolation (with a test date more than 10 days ago).

    When can I apply for a Covid Recovery Certificate?

    Your symptoms must have started (or you must have had your test) more than 10 days ago and you need to have been more than 48 hours without symptoms before you can apply.

    How do I know Medicspot's Covid Recovery Letters will be accepted for travel?

    We have written hundreds of these letters for travel to the United States and have confirmed the requirements with the CDC directly. We advise you to check requirements on the CDC website before you travel (https://www.cdc.gov/coronavirus/2019-ncov/travelers/testing-international-air-travelers.html).

    What will my certificate contain?

    It will state that we have reviewed your test certificate and assessed your symptoms, which allow us to state that you appear to have recovered from Covid-19 and therefore have developed a natural immunity to Covid-19. This will be signed by a doctor fully registered with the UK General Medical Council. Our contact details are included if any verification is required. We don’t currently include QR codes; this isn’t a requirement of the CDC.

    When will I receive my Covid Recovery Certificate?

    This will depend on the delivery option you have chosen. Please see our main Covid Recovery page for more information. To avoid delays make sure that you meet the criteria for travel and include all the correct information, including your passport number and full name.

    I still have a cough and loss of smell, can I get a Covid Recovery Certificate?

    A loss of sense of smell or taste, and a dry cough, can last for many weeks. As long as these are improving, these won’t stop you from getting your documentation of recovery.

    What is the difference between a Covid Recovery Certificate, Proof of Immunity and Documentation of Recovery?

    A Covid Recovery Certificate and Proof of Immunity are the same documents, showing that you have recovered from Covid-19. When these are presented with your positive test result, this is called your Documentation of Recovery (according to the CDC).

    How do I calculate my isolation days?

    Day 0 is your first day of symptoms or a positive viral test. Day 1 is the first full day after your symptoms developed or your test specimen was collected. Although the quarantine rules allow some people to end isolation after 5 days, you are still required to not to travel for 10 days.
