More candidates stall here than anywhere else: the case needs evidence of real U.S. engagements, and nobody explains how to get an employer to put that on paper. Here is what the letter actually is, what it is not, and the free way O1DMatch turns employer interest into one.
One page, from a real U.S. company, saying it intends to engage you if you are authorized to work. It is non-binding — not a job offer, not a contract, and not a visa petition. Its power is evidentiary: an agent-based O-1 petition is supported by an itinerary of real prospective engagements, and each letter is one engagement made concrete.
You do not cold-email companies begging for paper. The sequence runs the other way: your profile and evidence record go up free, employers browsing the platform or receiving your application respond with an interest letter when they want to move — that is the platform’s native mechanic. Your job is the evidence record; the letter is how an employer says yes to it.
The platform in one sitting - where the interest letter fits in the whole flow.
The exact screens: what arriving letters look like and what accepting one does for your case.
How many letters an itinerary needs depends on the shape of your case — the agent side works that out with you; more real engagements is always stronger than fewer. Letters do not have a formal expiry, but stale intent reads stale, so recent letters carry more weight. And the honest one: no platform can promise an employer will respond — what a platform can do is put your record in front of employers whose part has been made small enough to say yes to, and answer you either way. Visa petitions are adjudicated by USCIS, and nobody can promise an outcome.
A one-page, non-binding statement from a real U.S. company that it intends to engage you if you are authorized to work. It is evidence for the itinerary behind an agent-based O-1 petition - not a job offer, not a contract, and not sponsorship.
In this context, yes - people say interest letter, letter of interest, and LOI interchangeably. What matters is the content: a real company, a real prospective engagement, stated intent, and a reachable contact.
There is no magic number in the regulations - the itinerary must show real prospective work across the visa period. More genuine engagements make a stronger case than fewer; the agent side shapes the right set for your situation.
No. The company signing an interest letter does not file the petition, does not pay a USCIS filing fee, and does not run an H-1B process. The case is filed through an authorized agent or petitioner.
O1DMatch is built so employers respond to candidates with interest letters as the platform’s native mechanic, and joining is free. What nobody can promise is a specific employer’s response or a visa outcome - petitions are adjudicated by USCIS.
