Dear Fadi,
At the Toronto Airport, while I was trying to get back to work in the US,  my existing TN Visa was arbitrarily removed on a technicality of a wrong designation being used by me as a “Director.” (The TN Visa was originally  based on my being a “Management Consultant”).
The immigration lawyers at Niren and Associates, in particular with the assistance of Fadi, was able to deconstruct the problem and resubmit a  fresh application on my behalf to the US Customs and Border Patrol adjudicators.
The matter was resolved in my favor and my TN Visa was re-issued for a period of three years as compared with original one  year. The process presented no problems and went smoothly.
As a layman I  am  sure I would not have been able to tackle this, as I was already finger -printed, photographed at US Customs. It had been an intimidating experience.
Your immigration law firm’s approach is methodical and provided me with the professional preparation for dealing with the concerned authorities. Therefore I highly recommend your firm.
B.I.
