HOW TO GET VISA TO CAMBODIA?
All Types of Cambodia visas You Should Know:
1. Tourist visas:
The tourist visa (T class) is best for those who know they will be staying 30 days or less. The 30-day tourist visa is available to travelers in advance or on arrival (for most nationalities) for a cost of $30 if you get it directly at the airport. The tourist visa is single entry only, and can be renewed once for an additional 30 days for a fee of between $30 and $50.
2. Cambodian “ordinary” visas (E class).
If you are considering staying in Cambodia for an extended period of time, you will need to apply for a 30-day E-class visa (not an online e-visa) when you arrive. This is also valid for 30 days and costs $35. The difference between the ordinary visa and the tourist visa is that the ordinary one can be extended indefinitely. After 30 days, when you go to extend your visa for longer stay in Cambodia with the extension as: a) EB visa extension. The EB business EOS covers most Cambodia expats, including those who are working and their partners and children, freelancers, and volunteers. b) EG visa extension. The EG visa extension is intended for those searching for employment, and can last 1, 3, or 6 months. Those who have had previous EB visa extensions may or may not be granted an EG visa, as they are not intended for those who have already been in the country long term. c) ER visa extension. The new retirement visa extension is meant for those of retirement age who can show documentation of retirement in their home country (such as a pension or Social Security) and prove that they have the funds to support themselves. ER visa extensions are usually only granted to those who are 55 and up & retired. d) ES visa extension. The ES visa extension is a student visa. Applicants for the ES visa extension need to provide a letter from a registered Cambodian school, as well as evidence of sufficient funds to support themselves. 
3. K-class visa.
The K-class visa is for those of Cambodian descent who hold a foreign passport. It is a free lifetime visa, although you will almost certainly be asked to pay an unofficial “facilitation fee” to get it. Bring any documents that show that you have one Khmer parent, such as a birth certificate, marriage certificate, family book, or Cambodian ID card. A Khmer last name and ability to speak Khmer may be enough—along with a $20 bill, of course.
4. B-class visa.
The B-class visa is for employees of organizations that are in Cambodia at the government’s invitation, such as the United Nations or World Health Organization, and need to be organized in advance by the employer.
5. C-class visa.
The C-class visa is a free visa for employees of international NGOs that have a memorandum of understanding (MoU) with the Ministry of Foreign Affairs (these used to be B-class visas, but no more). The INGO will need to apply in advance for your visa and have a representative meet you at the airport on arrival with a letter of attestation from the Ministry of Foreign Affairs.
Who needs a visa for Cambodia?
Most foreign visitors will need a visa to Cambodia, including infants and children (the price is the same as for adults). If you are from an ASEAN country and hold a passport from Brunei, Indonesia, Laos, Malaysia, Philippines, Singapore, Thailand, or Vietnam, you do not need a visa to enter Cambodia for between 14 and 30 days depending on the country. Officially, if you are from Afghanistan, Algeria, Saudi Arabia, Bangladesh, Iran, Iraq, Nigeria, Pakistan, Sri Lanka, or Sudan, you are not eligible for a visa on arrival and will need to apply in advance at the closest Cambodian embassy in your home country (although all but citizens of Nigeria can apply online for an e-visa a minimum of 20 working days in advance). For citizens of these countries, the visa requirements are far more onerous. At a minimum, you’ll need a return ticket and sponsor letter or letter of invitation from an employer or organization. Be aware that although residents from African countries are technically eligible for Cambodia visas, many are denied on arrival.
How To Apply Cambodian visa?
What you need to apply for a visa to Cambodia:
A passport that is valid for at least six months and has at least one blank page
Cash in US dollars
Where to apply for a Cambodian visa:
At the airports. If you’re from most countries, you can get a visa on arrival at the Phnom Penh, Siem Reap, and Sihanoukville airports. You do not need to do anything in advance — you’ll be given an immigration card to fill out on the plane and you just need to get in line on arrival with your immigration card, cash (in US dollars), and passport. There is an ATM at the airport in arrivals that dispenses US dollars if you don’t have any on hand.
Apply Online. Another option is the Cambodian e-visa, which can be obtained online. It is only offered for the tourist (T class) visa and is available to those entering Cambodia at the Siem Reap, Phnom Penh, and Sihanoukville airports and the Bavet, Poipet, Stung Treng, and Cham Yeam land border crossings. It is only available to citizens of the countries for which visas on arrival are available, which is a nebulous and oft-changing list. You can apply through the official online government visa processing center, but be aware that visas can and do get lost in their system, so make sure to apply at least a week in advance. The cost is $40 for a 30-day visa.
