Online visas, also known as E-Visas, are visas obtained through the assistance of the Internet. The entire process is completed online, including the visa application, submission of relevant documents, and the virtual payment. 

The decision for approval is also communicated online. Many travelers prefer to obtain their visas online because they can be approved before getting to their destination. This also avoids the stress of completing paperwork and documentation at the airport to receive your visa on arrival (VOA).

Appropriately named, visas on arrival refer to the visas issued after applying for a visa upon arrival in a foreign country. Authorities of the given government will look over the traveler's passport and collect application fees. 

Once approved, the visitor is issued documentation. Depending on the country you visit, additional records of identification may be taken, such as biometrics. 

These collections are used to review the visitor's criminal and immigration history. Just like how it is for standard visas, the visa on arrival is printed onto the passport. The passport must have enough empty pages for a stamp to be issued. All of these steps take place at the airport or point of entry. Some people find that obtaining a visa on arrival is more straightforward due to the lack of so many in-person requirements. 

There is also no need to go to the country's embassy before arrival. As of June 2021, a total of 36 countries offer visas on arrival.

An Electronic Travel Authorization, abbreviated as (eTA), is an entry requirement for foreign nationals who are visa-exempt. The eTA is virtually connected to the traveler's passport and is considered valid either until the passport expires or for five years; it really depends on which occurrence happens first. 

Again, depending on the areas where you visit and return, the laws regarding eTAs may vary. Do your research before embarking on new territory to avoid potential mistakes.

To apply for your passport, you need to have your Social Security Card. You can order a replacement if you are not sure where your card is. Replacements can be ordered while you apply for your passport. 

You must also have additional documents proving your citizenship, identity, and passport confirmation. Fees vary based on country.

Depending on where you will be returning home, you can be barred from reentering. Some nations allow grace periods, and others begin charging from the first day of expiration. 

The fines depend on your home country, but they most often correlate with a set amount of time you will have to have overstayed your visa.
