The US employment visa system is rationed, capped, and picky, and a wrong assumption at the sourcing stage can wreck a placement three months later, when the offer letter is signed and the candidate still can't legally start.
That gap between what hiring managers think they're buying and what the system actually delivers is where deals fall apart.
The myths below come up again and again in agency conversations, and each one is worth correcting before a client asks why their new hire is stuck abroad.

The H-1B Lottery Is No Longer a Lottery
Recruiters still talk about the H-1B as a coin flip. That framing is out of date. Starting with FY 2027, USCIS moved to a weighted selection process that tilts the odds toward higher-skilled and higher-paid roles, while still leaving room for employers at every wage level.
In practice, a candidate offered a Level IV prevailing wage now gets more entries than a Level I candidate for the same role. That changes how you should pitch salaries to clients. A borderline offer that would have squeaked into the old random draw may now sit in the bottom tier and go nowhere.
The cap itself hasn't moved. Advise clients on wage banding before the March registration window, not after.

An Internal Transfer Is Not a Rubber Stamp
The L-1 visa gets sold internally as the easy option. Same company, same employee, different office. What could go wrong?
Plenty. Adjudicators are back to scrutinizing specialized knowledge cases hard, and the denial rate on L-1 categories moved in the wrong direction between the end of FY 2024 and the end of FY 2025, according to recent Forbes analysis of USCIS data. The gap between an approved transfer and a denied one usually comes down to documentation quality, not the employee's actual skill set.
For recruiters sitting between a UK office and a US hiring manager, the takeaway is simple. Don't promise a client that an L-1 will move faster than an H-1B just because the person is already on payroll.
It might. It might not. The evidence file has to do the work.

The Green Card Queue Is Not a Backup Plan
A common pitch to nervous candidates goes like this: get in on an H-1B, then convert to a green card. Clean on a whiteboard, messy in practice.
Employment-based green card categories have annual caps too, and they run out. The EB-1, EB-2, and EB-3 categories were all unavailable for the rest of FY 2025 after their annual limits were hit before the fiscal year closed. Cases in those categories sat until October.
For a candidate born in a heavily oversubscribed country, the wait can stretch across years, not months. Recruiters who position permanent residency as a near-term follow-on to a temporary visa are setting up disappointment. Frame it as a long project the employer is committing to, not a switch that gets flipped after year one.

The US Employer Carries Most of the Paperwork, Not the Candidate
Candidates arrive at intake calls expecting to hand over passports and transcripts and be done. That's a fraction of the work. The heavier lift sits with the sponsoring employer, and recruiters who don't brief the client on that end are the reason cases fall apart late.
The employer side of a typical employment petition includes items the hiring manager may not have thought about:
-
Prevailing wage determinations. The Department of Labor sets the floor for what the role must pay in the specific geographic area, and the offer letter has to match or beat it.
-
Labor condition attestations. The employer signs off on wage, working conditions, and notice to existing staff before the petition is even filed.
-
Corporate proof. Tax returns, org charts, and financial statements that show the company can actually pay the wage and support the role.
-
Job description discipline. Duties written for a job ad rarely survive adjudication. The petition version has to line up with a recognized occupational classification.
If the US employer treats this as HR admin, expect delays. Recruiters who flag it as executive-level work when the search kicks off end up looking prescient. An employment-based immigration attorney on the client's side is worth introducing early, not after a request for evidence lands.
-
Location on the Offer Letter Actually Matters
The last myth is the most avoidable. Recruiters treat the US office address on an offer letter as a formality, something HR will sort.
In reality, wage floors are set by geography. Consular processing routes depend on the candidate's home post. Some visa categories require the employer to have a qualifying physical presence in the US, not a coworking desk and a P.O. Box.
A remote-first client that lists an address in a low-wage metro to trim the prevailing wage number is asking for a site visit and a denial.
Nail down the intended work location before the offer letter goes out. Confirm the wage level against that location. Confirm the client has a real footprint there. Doing this at the sourcing stage saves the case at the adjudication stage, and it saves the placement fee.
Where Recruiters Add Value
None of this makes US placements a bad line of business. It makes them a specialist one. The agencies that win cross-border tech, healthcare, and finance searches are the ones that treat immigration as part of the workflow, not a client problem to be handed off after the offer.
Know the current rules. Push clients to think about wages, locations, and timing before candidates get their hopes up. And when the case reaches the point where legal advice decides the outcome, refer out early. Candidates remember which recruiter told them the truth about the timeline, and clients remember which one kept the hire from falling apart in month three.
