Note #18: Border Crossing Red Flags
Things that get you pulled into secondary inspection:
One-way ticket with no return/onward flight
Passport full of stamps from "suspicious" countries
Can't name your hotel address
Arriving with no luggage (looks like you're working illegally)
Tourist visa but laptop and work setup visible
Got detained 4 times in my first 2 years.
Now I:
Always book refundable return flights
Dress like I'm on vacation (no laptop bag at immigration)
Have hotel confirmations ready on phone
Say "vacation" not "digital nomad"
Border agents aren't your friends. Give them no reason to ask questions.
