The Short Answer: Visa Status and C2C Eligibility
All three—H1B holders, EAD holders, and green card holders—can legally do C2C (corp-to-corp) contract work in the United States. The catch: compliance rules, tax obligations, and employer liability concerns differ sharply by visa type, and many recruiters and vendors will reject you anyway out of legal caution.
This is the #1 confusion point for immigrant consultants. You meet the legal requirements, but gatekeepers don't know the law, so you hit friction at every step.
H1B Holders and C2C: What the Law Actually Says
H1B visa holders can lawfully perform C2C contract work as long as the work itself is not prohibited by their visa terms. Your H1B is tied to a specific employer and role, but your work authorization (employment eligibility) is independent of that sponsorship.
The key distinction: you cannot work for a different employer in violation of your H1B conditions (e.g., working in a different role or field than authorized). But if your C2C contract is for work within the scope of your H1B authorization, it's legal.
Practical friction point: Most C2C vendors and end-clients are risk-averse. They'll ask for green card proof or EAD approval letters because they don't want to deal with ambiguity. Even though your H1B work authorization is valid, you may face rejection or be asked to get a legal opinion letter from an immigration attorney (which costs $500–$2,000).
EAD (Employment Authorization Document) Holders: The Safest Position
If you're on an EAD (typically from an I-485 pending, asylum, or other category), you have unrestricted work authorization. You can take any legal employment, including C2C contracts, with no visa sponsorship constraints.
From a compliance perspective, EAD is the cleanest position for C2C work. No job category restrictions. No visa petition ties. You're a work-authorized individual, period.
Practical advantage: Most C2C platforms and vendors accept EAD without question. Your approval notice and work-eligible documentation are straightforward. You face fewer application rejections tied to visa status.
Green Card Holders: Full Freedom, Full Tax Liability
Green card holders (lawful permanent residents) have zero restrictions on employment type or C2C contracts. You can work for any entity, in any role, without sponsorship or visa category limits.
However, green card status comes with permanent U.S. tax residency. If you're doing C2C contracts, you'll file as a self-employed individual, subject to both federal and self-employment taxes. That's a financial reality, not a legal barrier—but it's worth knowing upfront.

The Real Barriers (They're Not Legal)
The law is clear. Vendors and end-clients often aren't. Here's what actually blocks immigrant consultants from C2C work:
- Vendor risk aversion: Staffing firms and body-shop vendors require green card proof or explicit legal clearance because they don't want to navigate H1B ambiguity, even though it's legal.
- Client compliance teams: Fortune 500 procurement teams have blanket policies. They don't distinguish between visa types—they just say "no visa sponsorship" and filter everyone out.
- Insurance and contractor classification: Some vendors require proof of work authorization or green card status to qualify for their E&O insurance policies.
- Background check failures: Some background screening companies flag non-U.S. citizens for additional scrutiny, which can delay contracts by weeks.
None of these are legal requirements. They're business risk management by people who don't know immigration law.
Practical Steps: How to Navigate This
- Get clarity in writing from your immigration attorney. If you're H1B and pursuing C2C, ask your immigration lawyer to confirm the specific C2C work falls within your visa authorization. A one-paragraph legal opinion letter ($300–$500) becomes your proof.
- Prepare documentation upfront. Have your EAD approval notice, green card, or H1B visa documents ready. Most applications ask for this; answer directly and early.
- Work with vendors who don't filter by visa status. Smaller staffing firms and niche C2C platforms are less rigidly compliant-obsessed. See our review of C2C platforms to identify ones with low friction for immigrant contractors.
- Disclose upfront with end-clients. Don't wait for a background check to reveal your visa status. Tell the hiring manager in your first conversation: "I'm X visa status, fully work-authorized for U.S. employment." Clarity kills awkward surprises.
- Consider your tax structure. If you're doing high-volume C2C work, consult a tax CPA (not just your immigration attorney). Self-employment tax is substantial, and some visa categories have implications for future green card or citizenship timelines.
EAD vs. H1B vs. Green Card for C2C: Side-by-Side
| Visa Type | Legal C2C Eligibility | Client Friction Level | Tax Complexity |
|---|---|---|---|
| H1B | Yes (within visa scope) | High (vendor caution) | Moderate (sponsor reporting) |
| EAD | Yes (unrestricted) | Low (cleanest path) | Moderate (self-employment) |
| Green Card | Yes (no restrictions) | Low | High (full U.S. tax residency) |
EAD is the pragmatic sweet spot: legal unrestriction + minimal vendor friction + manageable tax obligations.
What Happens If You Don't Disclose?
Don't. Misrepresenting your immigration status on a C2C contract or background check creates federal liability for both you and the vendor. If it surfaces later (and it usually does during compliance audits), you risk visa revocation and deportation. The contract payout isn't worth that risk.
Transparency is faster and cheaper than legal fallout.
Speed Matters in C2C Too
C2C contracts move fast—often filled within 48 hours of posting. Visa status confusion will cost you opportunities. If you're H1B, get your legal opinion letter now. If you're EAD or green card, have your documentation template ready and paste it into applications before anyone asks.
The first applicant who answers the visa question cleanly wins. Delays kill contracts.
GiraffyReach detects fresh C2C contracts the moment they go live and auto-applies before vendor gatekeepers filter by visa status. If you're authorized to work in the U.S.—regardless of visa type—speed and clarity are your competitive edge. Compliance rules shouldn't block you. Speed should win.
