FAQ's
frequently asked questions
Explore our faqs or reach out to understand how our financial guidance works.
What is an apostille and why do I need it to use my documents in Mexico or the U.S.?
An apostille is an official certification that verifies the authenticity of a document issued in one country so it can be legally recognized in another. If you have U.S. documents that need to be presented in Mexico — or vice versa — an apostille is required.
Without it, no public or private institution will accept your document.
At MEX-USA Legal Services, we handle this process quickly and efficiently, so you don’t need to visit any government offices.
How does a power of attorney work from the U.S. and what is it used for?
A power of attorney allows you to appoint a trusted person in Mexico or anywhere in South America to act on your behalf legally — including buying or selling property, handling legal procedures, collecting inheritances, representing you in court, or opening, managing, or closing bank accounts, among other actions.
You can complete this process from the U.S. without traveling to Mexico — you only need to sign the required documents. The power of attorney is then apostilled and becomes valid for use in any Mexican or Latin American institution.
My birth certificate has errors — can I correct them without going to Mexico?
Yes. Errors in birth certificates — such as misspelled names, incorrect dates, or missing information — are among the most common issues that can block dual citizenship, inheritance, or property-related processes.
We coordinate the correction process directly with the Civil Registry in Mexico through legal representation, without requiring you to travel. Once corrected, your document will be fully valid for any legal procedure you need.
My dual citizenship application was rejected at the consulate — what’s next?
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s,when an unknown printer took a galley of type.
How long do these processes take and how will I be kept informed?
Timelines vary depending on the type of service: an apostille may be completed within a few business days, while record corrections or powers of attorney may take several weeks depending on the state in Mexico.
What we guarantee is constant communication — we keep you updated at every stage so you are never left in uncertainty. Everything is handled remotely, so you don’t need to take time off work or wait in lines.
What do I need to start? Can I begin the process from any U.S. state?
Yes, we serve clients across the entire United States. To begin, you only need to share your situation and available documents — we take care of the rest.
We conduct an initial assessment to identify exactly what you need and provide a clear plan with costs and timelines. No surprises.
