90-day checklist

Your first 90 days in Mexico get a lot easier once you stop trying to do everything at once.

This checklist is here to keep the order visible. Not because every resident needs the exact same day-by-day timeline, but because the dependency chain is real enough that doing the right task in the wrong week can still cost you time.

What it helps you do

Translate a messy first-three-month period into a simple phased checklist.

Core questions answered

  • What should happen in days 1–14, 15–30, 31–60, and 61–90?
  • Which dependencies matter most across CURP, SAT, banking, and IMSS?
  • When should the reader switch from free pages to the PDF kit?

The order

This is the sequence the admin setup guide is built around.

Resident card first. Then CURP. Then RFC. Then the tools and services that depend on those pieces being stable. Once you accept that this is a chain, the whole 90-day period starts looking less random.

PhaseWhat to prioritizeWhy this phase exists
Days 1–14Confirm resident-card data, verify CURP generation and spelling, and begin assembling strong proof of address.This is the identity-foundation phase. If your data is wrong here, later agencies inherit the problem.
Days 15–30Book or attend SAT for RFC if needed, especially if work, invoicing, or formal admin is coming quickly. Obtain NSS once CURP and email are ready.This is the “first real unlock” phase. You move from general residency into tax and health-system access.
Days 31–60Handle e.firma, generate CSF using the right path, and start preparing for bank onboarding with a complete packet.This phase makes later admin smoother instead of more repetitive.
Days 61–90Complete bank onboarding, choose the IMSS path that fits, and clean up any trailing document gaps.This is where the setup starts feeling more like a life than a sequence of appointments.

What belongs in each phase

Think priorities, not perfection.

Days 1–14

  • Confirm resident-card data is correct.
  • Check whether CURP exists and validate it.
  • Compare CURP against passport and resident-card spelling.
  • Start building a clean address-proof packet.

Days 15–30

  • Book SAT appointment if RFC is urgent for your situation.
  • Prioritize RFC especially if you will invoice, formalize tax identity, or need banking to move quickly.
  • Get NSS once CURP and email are ready if IMSS planning matters soon.

Days 31–60

  • Attend the e.firma appointment with USB and originals.
  • Use the right CSF path: online self-service first if credentials are ready, then SAT ID or Office Virtual if not.
  • Prepare the bank packet with branch confirmation, not just website confidence.

Days 61–90

  • Finish bank onboarding if the packet is ready.
  • Choose between IMSS family insurance, the independent-worker route, or a hybrid strategy.
  • Clean up any lingering identity or document mismatches before they follow you further into daily life.

Failure modes

These are the mistakes most likely to make the 90 days feel longer than 90 days.

They’re not dramatic. They’re just expensive in the currency of repeat appointments and low-grade stress.

Watch for these

  • Treating CURP as optional instead of foundational.
  • Going to SAT with weak proof of address.
  • Missing the 10-day window after an incomplete RFC submission.
  • Booking e.firma without the required originals or USB.
  • Assuming bank websites use current immigration language in a fully reliable way.
  • Assuming IMSS family coverage starts immediately after enrollment.

If you want this checklist in a tighter, more printable system, the First 90 Days Admin Setup Kit is exactly that.

The kit was built around this 90-day sequencing logic. It’s the version you keep open while you actually do the work, not just the version you nod at while planning.
