If you’re staying in Mexico longer than a tourist trip, three acronyms run your life: CURP, RFC, and FMM. Here’s what each is and the order to get them in 2026.
Last verified: May 6, 2026.
FMM — Forma Migratoria Múltiple (tourist permit)
- What it is: the 180-day tourist permit
- Cost: free if traveling air (built into ticket); ~$700 MXN at land borders
- How: filled at port of entry; immigration officer writes the days you got
- 2024 change: immigration officers no longer automatically grant 180 days. They can grant 30, 60, 90 — entirely discretionary. Push for 180 if you can
- Cannot: open a bank account, sign a long lease, work, or get a CURP/RFC on FMM alone
Temporary Resident card (Residente Temporal)
- What it is: 1–4 year residence permit
- Apply: at Mexican consulate in your home country (NOT in Mexico)
- Income proof: ~$4,300 USD/month for 6 months OR ~$72,000 USD savings for 12 months (rates change yearly with UMA)
- Cost: ~$50 USD consular fee + ~$300 USD canje fee (in-Mexico processing)
- Timeline: 2–4 weeks consular + 6–10 weeks for canje after arrival
CURP — Clave Única de Registro de Población
- What it is: 18-character unique identifier (like a social security number)
- Required for: bank account, RFC, getting paid, signing leases, healthcare
- Cost: free
- Get it: SAT/RENAPO website if you have a residency card; or in-person at any Modulo INE
- Timeline: same-day usually
RFC — Registro Federal de Contribuyentes
- What it is: Mexican tax ID — required to invoice clients, get paid as freelancer, and increasingly for bank account opening
- Required: residency card + CURP first
- Get it: SAT (Servicio de Administración Tributaria) website or appointment
- Cost: free
- Timeline: 2–4 weeks if appointment-based; some online portals same-day
Order of operations
- 1. Get FMM at port of entry (if just visiting)
- 2. Apply for Temporary Resident at consulate before traveling (if staying)
- 3. Arrive in Mexico, do canje within 30 days of arrival
- 4. Get CURP once residency card issued

Practical tips that make the difference
- Plan in advance: book major attractions + restaurants 4-8 weeks ahead in peak season. Cancellation is usually free up to 24-48 hours before arrival
- Use the local apps: country-specific transport, payment, and food delivery apps work better than generic international ones. Examples: Grab in SE Asia, Bolt in Europe, DiDi in China, MTR app in Hong Kong
- Carry small cash: card acceptance varies; small amounts in local currency saves moments. Always have $50-100 equivalent in cash for emergencies
- Travel insurance: even a $50 policy saves you from $5,000+ medical bills. Doctor visits abroad average $30-150; emergency rooms can run $1,500-15,000 for serious cases
- Photograph everything important: passport, BRP, important addresses, emergency numbers, insurance policy, contact details. Store in cloud + offline
- Get an eSIM before you fly: avoid paying $10-15/day in roaming charges. Airalo and Holafly start at $4 for short trips
Common mistakes to avoid
- Booking too tight: build 30-50% buffer between commitments. Strikes, weather, jet lag all cause delays
- Skipping local etiquette: brief research on greetings, tipping, and dress codes saves embarrassment
- Eating at tourist-trap restaurants near monuments: walk 2-5 minutes off main squares for better food at lower prices
- Underestimating walking: most European + Asian cities are walked, not driven. Comfortable shoes essential. Plan for 15,000-25,000 steps per day on active travel
- Ignoring transit cards: city travel cards (Oyster, Suica, Navigo, etc.) are 30-50% cheaper than single tickets
- Booking accommodation by stars rating only: read reviews from past 6 months specifically. Old reviews can mislead about current state
Money-saving strategies
- Free walking tours: most major cities have tip-based walking tours. Excellent way to orient yourself + learn history. Sandeman, Free Tour brand operate in 30+ cities
- Lunch menus vs dinner: many restaurants offer lunch fixed-price menus 30-50% cheaper than equivalent dinner
- Public transport day passes: usually 2-3x cheaper than 4 single tickets
- Book flights mid-week, fly Tuesday/Wednesday: typically cheapest days. Avoid Friday and Sunday flights
- Hostel private rooms: 20-30% cheaper than hotels for similar quality. Many have great social common areas
- Local SIM cards in 3+ week stays: cheaper than eSIM for longer stays in single country
When to consider a guide or local expert
For more complex situations — multi-country tax planning, complicated visa applications, or substantial property purchases — engaging a regulated professional saves money and stress in the long term. Look for: OISC-registered immigration advisers (UK), Spanish gestores (Spain), German Steuerberater (Germany), or cross-border tax specialists (any country). For travel-specific questions, local certified tour guides offer expertise generic guides can’t match.
