Meet the Founder

Built from inside immigration practices, not from the sidelines.


For more than 20 years, Dayana Valero Halten has worked inside immigration practices — first as a member of their teams and, since 2015, as the contract paralegal and partner boutique firms bring in to handle employment-based cases and grow their practices. When you work with Valero Legal, you work with her.

Keep the Work

Keep the case, build the relationship.


When you refer out a case, more than one matter is at stake.

A single employment-based case can bring years of work: subsequent filings, family representation, and additional hires for the same employer. Referring it out can mean handing over the relationship — and the revenue that follows.

  1. PERM labor certification
  2. I-140 petition
  3. Adjustment of status for the employee and family
  4. Future hires, renewals, and referrals

Your firm’s reputation is in the details. That’s where we work.

Client Experiences

What firms say about working with Valero Legal


Dayana began her immigration career at my firm, assisting with asylum, family-based cases, and waivers. After expanding her experience and founding Valero Legal, she became the person I turned to for employment-based matters I had previously referred out.

Her support allowed me to keep those cases within my practice and offer my clients more. Beyond her experience, I value her integrity and the personal responsibility she feels for the work entrusted to her. She cares about the people behind the cases, and it shows. I trust Dayana and Valero Legal wholeheartedly.

Irving G.Founder, Irving J. Gonzalez, P.A.

When we unexpectedly lost two paralegals, Valero Legal stepped in to support all of our employment-based cases and many of our family-based matters. For two years, they provided the continuity we needed while we rebuilt our in-house team.

We’ve worked with Dayana and Valero Legal since early 2018 and continue to rely on them for employment-based matters, specifically PERM, where experienced paralegal support has been particularly difficult to find. Dayana is deeply invested in the cases, our firm’s success, and the outcomes for our clients. That level of care is what makes this a lasting partnership.
