US Work Visa

What US Work Visa does

Mark A. Ivener, A Law Corporation, doing business as US Work Visa, was a Los Angeles-based sole-practitioner business immigration law firm providing legal representation to corporate counsel, international investors, business executives, and entertainers. The firm handled the full spectrum of business immigration matters, including H-1B specialty occupation petitions, L-1 intracompany transfers, E-1/E-2 treaty trader and investor visas, H-1B1 free-trade-agreement visas for Chilean and Singaporean nationals, EB-5 investor green cards (minimum investments of $800,000 in TEAs or $1,050,000 elsewhere), employment-based permanent residence, and I-9 employer compliance audits. Service delivery was anchored at a single headquarters office at 11620 Wilshire Blvd, Suite 900, Los Angeles, with historical satellite presence in New York, Tokyo, and Vancouver, and was organized around founder Mark A. Ivener personally.

The firm operated on a professional services fee model — billing per case for legal representation across visa and green card matters, with no subscription, software, or technology platform involved in service delivery. Client acquisition depended on Chambers USA rankings, Avvo, Martindale-Hubbell, Best Lawyers, and Citwealth recognitions, supplemented by authored publications including the Handbook of Immigration Law PDF e-book and multilingual immigrant guides, plus articles in HR Magazine, The Deal, Acquisition International, Offshore Investment Magazine, The Practical Tax Lawyer, and California International Law Journal. Customers were segmented across four personas: corporate legal counsel and HR professionals (H-1B cap, L-1, I-9 compliance), international investors (EB-5, E-2), business executives and professionals (O-1, specialty occupations), and entertainers; segmentation approach was horizontal.

The firm officially ceased operations on August 11, 2025 following Mark A. Ivener's retirement from the practice of immigration law. A formal succession referral was established with David R. Fullmer, a former partner now at WR Immigration, to absorb ongoing client matters including work visas, investor visas, and EB-5 cases. The firm is now closed, and the website at ivener.com is maintained as a historical archive.
