US Announces New Visa Procedures in Mexico as of January (MexiData.info)
Because the collection of biometric information will take place at the ASC, applicants who are required to visit both the ASC and the consular section should spend less time at the consular section than they have had to in the past.
It is my understanding that the biometric enrollment part of the application process was simply bolted onto the older process and required a separate fee.
Many on both sides of the border hope the attempt to streamline the process is successful.
