Can I get denied entry?

Yes. If an immigration officer suspects you are living in the country illegally via repeated visa runs, they can refuse your entry. Always have proof of funds and a clear travel plan.

Are land borders better than flying?

Land borders are significantly cheaper ($50 vs $200+) but are more physically exhausting. If you have the budget, flying to a neighboring country for 48 hours is less stressful and carries a lower risk of being flagged for a 'visa run' pattern.

How to do a Visa Run in Southeast Asia

A visa run involves exiting a country and re-entering to reset your tourist entry stamp or activate a new visa. To do this successfully, ensure you have proof of onward travel, at least six months of validity on your passport, and check the current local regulations for 'back-to-back' entry limitations.

Check the entry rules for your destination. Countries like Thailand and Vietnam have specific policies regarding how many times you can enter by land versus air. Use the official government e-visa portal or embassy website to confirm if you are allowed an immediate re-entry.
Book a reliable border-run service. If doing a land border crossing, pay for a dedicated van service (typically $30–$50). They handle the logistics, know exactly which border post is open, and ensure you get back to your starting city in one day.
Prepare your paperwork. Carry your passport, two passport-sized photos, and enough crisp, clean US dollars for visa-on-arrival fees. Always print out your proof of onward travel (a bus, train, or flight ticket out of the country) as immigration often asks for it.
Complete your exit and entry. Approach the departure window first to get your exit stamp. Once you have cleared, walk through no-man's land to the destination country's entry gate. Complete your arrival card, pay the fee, and ensure you receive the correct stamp duration in your passport before leaving the booth.
