The 32-year-old is the third former West Indies international in the last two years to be chosen for the US in an ICC tournament squad, reports CMC.
The Jamaican-born joins Adam Sanford and former US captain Neil McGarrell, who have both been dropped following US's 15th place finish in their most recent event, the World Twenty20 Qualifier last November.
Lawson once took a hat-trick for the West Indies in his 13-Test career but has not appeared for them since the opening Test in Brisbane against Australia in November 2005. His test career also includes 6/3 against Bangladesh and a career-best 7/78 to demolish Australia in the Caribbean.
He has not appeared in a USACA tournament since 2011 and has been playing in private T20 tournament around the country as well as club cricket in New Jersey and New York.
Lawson moved to the US in 2010 and qualified to play for US this year based on the ICC's four-year residency requirement.
