In order for a birth certificate, marriage certificate or death certificate from any state (USA) or province (Canada) or any document from any country that belongs to the treaty and (I do not recal the name) for them to be accepted as legitimate need to have the correct apostille stamps, when dealing with these types of documents try to have a family or friend in the US or Canada or other country ship the documents via FedEx, UPS, or DHL the Mexican postal service is not reliable, I have teceived lettets that were sent at the end of October and they arrived in late April, specially when time is of the esence but in order to be a little prepared bring certified copys of birth certificates and mariages or better apostilled, specially if you travel in South America.
