“Authorized to work in the US” on a remote job ad is a request for US work authorization that you already hold, so a developer living in Europe without it is normally screened out unless the employer says it hires abroad. The same applies to its neighbours on the page: “Remote (US)”, “H-1B sponsorship available”, “TN visa” and “US business hours” each limit the pool in a different way.
TL;DR:
- “Authorized to work in the US” most likely points to the Form I-9 check that US employers run on every hire for employment in the United States (per USCIS, the I-9 itself)
- TN status is for Canadian and Mexican citizens only, so citizenship of one of the 27 EU member states does not qualify on its own (per USCIS, EU country list)
- “H-1B sponsorship” describes what a US employer will file, not a right to work for it from abroad
- “Remote (US)” limits where you live; “US business hours” limits when you work
This is a reading guide for developers who live in the EU or EEA and browse remote ads. It is not tax or legal advice. It tells you what the wording asks for and which question to put to the employer, not what you are allowed to do. For the employment-structure side of hiring abroad, see our guide to employers of record for remote developers in Europe.
What “authorized to work in the US” asks you for
Form I-9 is the paperwork behind the phrase. USCIS says all US employers must complete it for every individual they hire for employment in the United States, citizens included. The employee attests to their employment authorization and presents documents proving identity and authorization, and the employer examines them (per USCIS, Form I-9 page).
A job ad that says “must be authorized to work in the US” is therefore describing the status the employer expects to see. The usual meaning is that the company wants someone who already holds US work authorization, with no visa work for the employer. For a developer in Europe who holds none, the ad normally excludes you.
Take a typical line: “Candidates must be authorized to work in the US and cannot require sponsorship.” Read it in two halves. The first half asks for existing status. The second says the employer will not file a petition for you, which rules out the H-1B route described below.
Still, ask rather than guess. An ad is a summary written by someone else, and only the employer knows whom it will actually hire. One short message to the recruiter, sent before you spend an evening on a tailored application, costs less than guessing wrong.
H-1B and TN: what the visa names tell you
TN is the simpler case. USCIS describes the TN classification as one that lets qualified Canadian and Mexican citizens seek temporary entry to the United States to engage in business activities at a professional level. If your passports are all from EU countries, an ad that mentions a TN visa is not written for you.
H-1B is for people who will perform services in a specialty occupation, and the US employer files the petition (Form I-129) on their behalf (per USCIS, H-1B page). When an ad says “H-1B sponsorship available”, it describes what the company will file for a hire who is going to work in the United States. It is not an offer to employ you from your flat in Valencia.
H-1B conditions change. The USCIS page carried active alerts about rule and fee changes when this article was checked on 31 October 2026, so do not rely on this article, or on a forum thread, for current terms. If an ad turns on H-1B and you care about the details, read the USCIS page itself.
”Remote (US)” and “US business hours”: location versus clock
These two phrases look alike and limit different things.
“Remote (US)” or “Remote - North America” is a location limit. The employer is telling you where the employee must be based, and that decision is theirs. A short question settles it: “Is this role open to developers living in the EU, or only to US residents?”
“Must work US hours” or “during US business hours” is a schedule limit. From Europe, a US Eastern workday lands in your afternoon and evening, so the question becomes whether you want that day, and whether the team needs live overlap or works asynchronously. Ask: “What is the required overlap window, and is the rest of the day asynchronous?”
One practical rule helps. Treat a location limit as a closed door until the employer says otherwise, and treat an hours limit as a trade-off you can price yourself.
What a US-only badge misses
The Xeito Job Tracker browser extension checks the job page you are reading for US-only wording and shows a small badge near the apply button. It looks for seven kinds: US residency, US citizenship, US work authorization, H-1B-only sponsorship, TN-only, Remote (US) and US business hours. When one matches, the badge reads “US-only” and its hover text shows the first wording it matched. Its limits matter more than its list.
First, the check does not look for positive EU signals. When it finds none of its phrases, the badge usually reads “EU-remote”. A separate labelling step can make that more specific if the ad names an EU scope or a country, or change it to “Not 100% remote” if the ad reads as on-site or hybrid. These labels mean only that none of the listed US-only phrases appeared and, at most, that the ad’s wording mentions a place. They are not proof that the employer hires in Europe, and no flag is not proof that you can work for that company from Europe.
Second, it matches a fixed set of patterns. The H-1B flag matches the unhyphenated “H1B sponsorship” and “H1B visa” only, so “H-1B sponsorship” with the hyphen does not trigger it. Looser wording such as “EST timezone” or “overlap with US hours” does not trigger the hours flag. A bare “authorized to work in the US” with no “must be” in front of it does not trigger the authorization flag either. A page where it cannot read the job description is checked on the title and location alone, so the badge can still read “EU-remote”. Treat the badge as a quick filter for obvious dead ends and read the ad yourself either way.
A three-question routine for any US-looking ad
Before you tailor an application, find out whether the employer hires in your country at all. The careers page sometimes lists supported countries. When it does not, send one message to the recruiter with three questions:
- Where may the employee be based?
- Which clock hours are required?
- Is the contract with a local entity in my country, or as an independent contractor?
The third question matters because it shapes how you are paid and who handles local obligations. It is a question for the employer, not something this article can answer for you, and the answers are different in every country. A message such as “Is this role open to developers based in Europe, and would the contract be through a local entity or as a contractor?” does the job in one line.
FAQ
Can I apply from Europe to a job that says authorized to work in the US?
You can send an application, but the line normally asks for US work authorization you already hold, so an applicant living in Europe without it is usually screened out. The employer decides, so a one-line question to the recruiter settles it.
What does authorized to work in the US mean on a job ad?
It points to the employment eligibility check US employers run through Form I-9, where the employee attests to work authorization and shows identity and work-authorization documents (per USCIS). The ad is telling you the employer expects you to pass that check without help.
Can an EU citizen get a TN visa?
Not on EU citizenship alone. USCIS describes the TN classification as for qualified Canadian and Mexican citizens, so holding the citizenship of an EU country does not qualify you.
Does H-1B sponsorship available mean I can work remotely from Europe?
Not by itself. H-1B is a US nonimmigrant classification for specialty occupations that the US employer petitions for, so the phrase describes the employer’s willingness to file, not permission to work for them from abroad. Current H-1B conditions change, so read the USCIS page.
What is the difference between Remote (US) and US business hours?
Remote (US) limits where you may be based. US business hours limits when you work. The first is a decision by the employer, the second is a trade-off you can weigh yourself once you know the window.
If the Xeito extension shows no US-only flag, can I work for that employer from Europe?
Not necessarily. The extension looks for a fixed list of US-only phrases, plus a few wordings that name an EU scope, and it cannot confirm that an employer hires in the EU. A badge without a US-only flag means none of those phrases were found, nothing more. No badge at all means the extension showed no result on that page.
