Removal is the process of removing foreigners from the United States that are found either inadmissible or
deportable. Being removed is the actual process because of a specific reason. Being inadmissible or
deportable is related to the reason for why you are removed. These terms do not mean the same.
A deportable alien can be defined as any person who entered the United States illegally. However, a person how entered legally but breached the terms of the classification or visa (e.g. overstayed
a valid visa) is also a deportable alien. Deportability is related to a person already in the United State.
Being inadmissible is only related to individuals trying to enter the United States at a border crossing (.e.g. airport or land border).
A person being inadmissible does not qualify to enter the United States according to INA for e.g. conviction of certain crimes
or immigration fraud. There are many more reasons that qualify for inadmissibility.
An individual being inadmissible has two choices:
Be removed
Ask to withdraw the application for admission to the United States
Being removed or withdrawing an application can have very different implications in the future. If you enter the United States but are being detained, you can ask to voluntarily withdraw your application to enter.
