A very important lesson I learned is, you need to read all their guidelines to conduct the process smoothly and timely. They give a remarkable attention to details and they produce a quality documentation to be submitted to the Chinese embassy. Their price is reasonable especially at the beginning when they don't have enough information about the client. Once they have this information, I expect they won't charge like the beginning price. The people that I was communicating, specially Judelyn Zapico , was very professional, diligent, patient, focused and detail oriented and I am very grateful for all the support you provided me.
