When a person or persons belonging to any nationality wish to go outside their own country for some reason, one of the first things that they need to do is acquire a passport. A passport is usually an international travel document, normally issued by the government of a country to its legal citizens for the purpose of international travel, which verifies the identity and citizenship of its holder. It is used to travel between various countries and to visit other countries. The passport has several types depending upon the purpose for which it is required.

It is necessary to have a valid passport for international travel to ensure smooth transiting processes and to avoid being refused entry at the customs or immigration checkpoints. There are different kinds of passports available for international travel and these are called the Travel Document System or the DDS. They include the International Travel Card, the International Driver’s License, the International Parole Card and the Australian Passport. The International passports are taken after inspection at the foreign airports or any other points of entry. They are also taken when traveling between the U.S. states or when crossing the sea or air borders.

Passport for emergency travel: For those who need a passport urgently for any reason, such as urgent family arrangements or medical emergencies, it is advisable to obtain an emergency passport. These documents are generally valid for only 12 hours. The emergency passport may be renewed once it has been expired. It can also be replaced if lost or stolen.

Passport for business travelers: Like the passport for international travel, a business passport also must be acquired for visiting countries that require foreigners to have a passport for doing business. However, there are some additional stipulations that are specific to this type of passport. For instance, a business passport usually has to be drawn up or approved by the Department of Revenue in the U.S.A. The fee is not usually more than $100.

Passport for children: To enter Australia, you must have your child (children below eighteen years do not require a passport) accompany you in your country of origin or destination. You may get a child passport even if the child is not yet eighteen years old. However, for children who have already turned eighteen years old, they must still accompany their parents in order to obtain their own passport. There are certain children who do not meet the above criteria. In that case, they may apply for an additional child passport.

Passport for people without travel documents: People who do not have travel documents are usually referred to as national or unaltered aliens. These people can travel to most countries without needing to provide documentary evidence of their identity. However, they may have to show proof of residence in their country of birth in order to exercise certain rights and benefits provided to citizens of their country. For example, some immigrants receive welfare benefits and are eligible for working permits in the host country. Immigrants who are granted work permits have the right not to overstay their limited period of stay.
