Most Influential and Connected Professionals
A number of our ABIL members have served on the Board of Governors of AILA (the American Immigration Lawyers Association), the 11,000-member organization comprised of most U.S. immigration lawyers. This includes past national AILA presidents, members of various federal government agency liaison committees and/or testify before Congress on immigration matters. A number of our ABIL lawyers are also immigration law professors at prominent law schools and have written well known immigration treatises and textbooks.

Unified Source for Consistent Quality
Each of our 20 U.S. members is listed in two or more of the world’s established ranking services for immigration lawyers (Chambers Global and USA, Best Lawyers in America, International Who’s Who of Business Immigration Lawyers, Martindale Hubbell AV ratings, and more.)

Additionally, we have established a Service Level Standards Committee, so any ABIL member can be counted on for quality, timeliness in case preparation and filing, responsiveness and other core service standards.

ABIL’s Cohesive and Personalized Approach to Client Service
This is not your ordinary “Strategic Alliance.”
ABIL started several years ago as the exclusive Academy for prestigious firms, and has evolved into an entity that offers a single point of contact for customer needs, news alerts, staff training and other programs that benefit the client. Here are just a few examples:

  • Our internal list serve keeps all ABIL members in daily contact, so that we can gather up-to-the-hour information from members with specialized expertise.
  • We share information on important immigration legislation, and often work together to advocate for essential reform of business immigration policies.
  • We conduct joint training sessions for each other’s firms, and pool our legal and administrative resources.
  • For all U.S. and international locations we have an ABIL member or global affiliate who can provide a local in-person consultation or accompany an employee to an immigration interview or hearing.
  • We have amassed immigration-related blogs in one location and provide a service to media and researchers, who often call upon ABIL members for expert opinions or testimony.
