When deciding to immigrate to a new country, it is vital that all the required laws and procedures are followed.  Even new President-Elect of the United States, Barack Obama, has stated that if his aunt from Kenya has violated any US Immigration laws then she may be subject to deportation from the country:

Zeituni Onyango, half-sister of Barack Obama’s late father, was ordered to leave the U.S. four years ago after a US Immigration Judge denied her request for asylum from her native Kenya.

You can reduce the risk of  immigration deportation during the immigration process by ensuring that you comply with Federal Immigration Laws.  If you find yourself in unlawful status, it is essential to consult with an immigration lawyer who can navigate you through the maze of immigration regulations and procedures.

We do not know the whole story behind Barack Obama’s Aunt but her situation certainly warrants proper immigration representation which given her relation to the President Elect, I am sure she has.
