What Clients Are Saying About CoxEsq, PC

  • I hired CoxEsq to help me become a US citizen despite a couple of, ahem, blemishes on my record. I am very satisfied with their services because I have received accurate advice that had my interests at heart, good communication, reasonable fees, and successful outcome. But especially -ESPECIALLY- what I appreciate about David Cox is the treatment that you get as a foreigner and a client. None of the condescension that immigration attorneys often inflict on us foreigners in precarious situations. I highly recommend CoxEsq.
