Our Firm

Jonathan H. Lamb

“I have seen many changes in immigration law over the past three decades: some for the better, some not. In spite of these changes in the law, what has never wavered has been my commitment to my clients. I have made it a hallmark of my practice to render personalized service to each and every client. My team and I take great pride not only in the successes we have achieved over the years, but most importantly in the differences we have made in the lives of those we have represented.”

Since opening his practice in 1983, Jonathan Lamb has handled thousands of immigration cases in the Houston area and all over the United States. Together with his associates and staff, Jonathan is eager to assist his clients with any immigration matter they may be facing.

Prior to becoming an immigration attorney, Jonathan attended Columbia University for his undergraduate degree and the University of Connecticut for his Juris Doctor. After graduating from law school, Jonathan moved to Houston and served briefly as a general counsel attorney for Mullins, Box and Parish. During his time with that firm, Jonathan developed his passion for immigration law, which he ultimately pursued by opening his own law practice. For over three decades, Jonathan has consistently delivered successful case resolutions for his clients from all over the world.

Today, as Senior Partner of Lamb & Turner, PLLC, Jonathan continues to assist clients dealing with all kinds of immigration issues.
