As noted by @Kat this area in general is new, and adding in the complexity of your facts is really beyond the scope of this forum.
Having said that, in general, I would say the income does not qualify. In order to qualify, the income must be effectively connected income. The sourcing rules for this are covered in Code Sections 861-865. The general rule for personal services is based on where the services are performed. Based on your current facts, that appears to be Mexico. As a result, that would disqualify the income from qualifying for the Section 199A deduction.
I would also recommend that you consult with a foreign tax specialist depending on the $$ involved.
*A reminder that posts in a forum such as this do not constitute tax advice.
Also keep in mind the date of replies, as tax law changes.
