"Tony understands our business, our business needs, and our company values and philosophies. Tony always provides the different immigration options available to us (listing the pros and cons of each) and presents his recommendation. This educates me on the issue at hand so that I can educate our managers and employees. I have had several matters in which timing is an issue. Tony always tries to accommodate our company to meet these short deadlines."
