How many times can I do visa runs?

No official limit, but Thai immigration may question frequent runs. After 2-3 runs in 6 months, consider getting a proper tourist visa from a Thai consulate.

Can I stay overnight in Cambodia?

Yes, but it's not necessary for a visa run. If you do, stay in Poipet or take a taxi to Siem Reap (1 hour, $15). Just make sure to return and re-enter Thailand when ready.

What if Cambodia visa on arrival is rejected?

Very rare for tourists. Have $30 USD exact change, a passport photo, and 6+ months passport validity. If rejected, you can return to Thailand with your original stamp still valid.

Are visa run tours worth it?

No. Tours charge $50-80 for transport you can do yourself for $15-25. The only benefit is convenience, but you'll spend the same amount of time either way.

How to do visa runs from Bangkok to Cambodia

Take a bus or fly from Bangkok to the Poipet border crossing, exit Thailand, enter Cambodia with a visa on arrival, then immediately re-enter Thailand for a new 30-day stamp. The entire process takes 6-12 hours by bus or 4-6 hours by flight plus border time.

Choose your route. Bus via Poipet is cheapest at $15-25 round trip but takes 6-12 hours total. Flying to Siem Reap costs $80-150 round trip but only takes 4-6 hours including border crossing time. Avoid tour company visa runs - they're overpriced at $50-80.
Prepare required documents. Bring your passport with at least 6 months validity, a passport photo for Cambodia visa, and $30 USD cash for Cambodia visa on arrival. Have proof of onward travel from Thailand if asked (rare but possible).
Get to the border. For bus: Take Northern Bus Terminal to Aranyaprathet (150 baht, 4 hours), then songthaew to border (10 baht). For flight: Fly Bangkok to Siem Reap, then taxi to Poipet border (1 hour, $15).
Exit Thailand. Present your passport at Thai immigration. Get your exit stamp. Keep your departure card if you have one - you'll need it when re-entering.
Enter Cambodia. Walk 500 meters to Cambodia immigration. Fill out arrival form, pay $30 for tourist visa (30 days), get your passport stamped. You're now legally in Cambodia.
Immediately return to Thailand. Walk back to Thai immigration (same building complex). Present passport and get a new 30-day tourist exemption stamp. You're done - head back to Bangkok.
