Difference between ‘exclusive’ and ‘non-exclusive’ contracts for EB-1B?

In the EB-1B, a category designed for outstanding researchers and professors, the petition typically relies on an offer or contract with a qualifying academic or research institution. The difference between an exclusive and a non-exclusive contract lies in the degree of commitment the professional assumes with that institution.

Under an exclusive contract, the professional agrees to dedicate their services solely to that institution, without simultaneously working for other employers. This arrangement helps demonstrate the solidity and continuity of the relationship, reinforcing the seriousness of the employment bond.

Under a non-exclusive contract, the professional may maintain collaborations with other institutions or projects at the same time. This is a common option for those who hold a varied portfolio of partnerships, but it requires care: even here, it is necessary to show that the contribution to the petitioning institution remains meaningful and genuine.

Neither format, on its own, approves or disqualifies a petition: what matters is the consistency of the relationship and the supporting evidence. Since each case is evaluated individually, it is worth confirming the current requirements with USCIS and reviewing the contract with a specialist before filing.
