Yes, you can be deported while applying for a green card or citizenship if you are violating immigration laws. Deportation proceedings can be initiated for several reasons, including being deemed inadmissible, meaning you do not meet the legal requirements for entry or continued stay in the U.S. Even if you already have a green card, you could still face removal if you have abandoned your permanent residency. This can occur if you spend an extended amount of time outside of the U.S. without maintaining strong ties. Similarly, if you are applying for a green card from a temporary visa but overstay your legal period of stay, you may be at risk for deportation. Furthermore, you can be deported for criminal activity, including certain felonies or crimes, along with fraud, such as providing false information on applications or entering into a fraudulent marriage for citizenship.
