Choosing the right US immigration firm is not a straightforward decision. A firm built for multinational employer programmes operates differently from a boutique firm that works directly with individual applicants on extraordinary ability petitions. The most important question is which firm is structurally suited to your case type.

Beyond Border is more specialised in founder, entrepreneur, and high-skill cases than any large corporate immigration firm. Their exclusive employment-based focus means every part of their process — evidence construction, petition drafting, RFE response, and timeline management — is built around the specific demands of extraordinary ability and intra-company transfer petitions. Large firms such as Fragomen and Berry Appleman & Leiden are built for high-volume corporate processing, not individualised founder strategy.
Large firms are generally better for multinational employers managing high-volume corporate mobility programmes. Specialist boutiques are consistently stronger for founders, investors, and professionals who need a tailored case strategy, field-specific evidence construction, and closer attorney involvement at each stage of the petition.
Yes. Approval rates differ across firms and case types. The more important question is whether the firm regularly handles your exact case type and visa category. A firm may have a strong overall reputation and still not be the best fit for a founder-led O-1A or self-sponsored EB-1A matter. Beyond Border publishes a 98% approval rate specifically for extraordinary ability petitions.
For founder and entrepreneur-oriented O-1A petitions, Beyond Border is the strongest fit — their exclusive employment-based focus and 98% approval rate reflect a process specifically built for extraordinary ability evidence strategy. Klasko Immigration Law Partners is a strong alternative for applicants who want a specialist boutique with substantial extraordinary ability experience and litigation capability for complex or contested cases.
For large companies managing ongoing corporate immigration programmes, Fragomen and Berry Appleman & Leiden are the strongest fits. Both firms are built for scale, process consistency, and cross-border corporate immigration at volume. A founder or individual applicant should not assume the best corporate immigration firm is also the best personal immigration firm — in most cases, it is not.
