• Renouncing U.S. citizenship can have several disadvantages. Someone who renounces his U.S. citizenship is no longer entitled to any of the privileges that US citizens enjoy. Additionally, he may or may not be able to legally reside in the United States. People usually consider renouncing their U.S. citizenship if they are planning on moving to a country that does not allow dual citizenship, or if they were originally from another country and plan on going back.
  
  

Possibility of Continuing Tax and Military Obligations

• Even if you renounce your U.S. citizenship, you may still be subject to tax and military obligations. This means that you may still have to file taxes in the U.S., and if you are a male older than 18, you may still be subject to the draft. Additionally, if you are subject to any sort of criminal charges, you cannot escape those charges by renouncing their U.S. citizenship.
  
  

Possible Inability to Reside Legally in the U.S.

• If you renounce your U.S. citizenship you may no longer be able to legally reside in the U.S. Non-U.S. citizens who are not foreign nationals are not legally allowed to reside in the United States. Additionally, you may incur issues or delays if you are a frequent traveler to the U.S. It is also possible that you may no longer be allowed to enter the United States, but this situation is very rare. If you have not already been accepted as a citizen of another country, you may incur a status that is known as statelessness. Statelessness basically means that you do not belong to any country. This may make it difficult to obtain a passport, legally find a place to live, or to enjoy any freedoms that citizens of any country enjoy. Additionally, if you're caught residing in another country illegally, you may be deported back to the U.S. but not be allowed to stay in the U.S. either.
  
  

Possible Inability to Work Legally in the U.S.

• Non-U.S. citizens do not enjoy the privilege of legally working in the U.S. They are not protected by any sort of labor laws, including minimum wage law or workers compensation. Anyone who is caught hiring a non-U.S. citizen illegally will face severe legal consequences if found guilty. Therefore, many employers are reluctant to hire non-U.S. citizens even if they are legally allowed to work in the United States. Foreign nationals are the only non-U.S. citizens allowed to legally work in the United States. However, because of tightening legal restrictions and the condition of the U.S. economy many employers may not be willing to hire foreign nationals even though it is legal.
