Hi
If you were removed from the U.S. because you, for example, overstayed your visa, violated the terms of your status, or committed a serious crime (even if you had a green card), the United States expects you to remain outside its borders for some time to come. To that end, you will be considered "inadmissible" under U.S. immigration law, and thus not allowed to return to the U.S., for a number of years.
Once you have been deported, the United States government will bar you from returning for five, ten, or 20 years, or even permanently. The exact length of time depends on the facts and circumstances surrounding your deportation. (Most deportees are barred for ten years.) For the details,
Just to be clear, there is no way to simply reverse your deportation. If you violated the terms of your visa, for instance, that visa has now been canceled. If you committed a crime, or did something else that makes green card holders deportable, you no longer have U.S. lawful permanent residence.
In rare cases, where there was a miscarriage of justice or new information has come to light, you may be able to have your case "reopened" or "reconsidered."
But more likely, if you plan or hope to come back to the United States, you will need to start from the beginning, by first finding a basis upon which you're eligible for an nonimmigrant (temporary) or immigrant (permanent) visa, and then determining whether you can overcome your inadmissibility in order to successfully apply for it.
If you wish to apply for admission to the U.S. as an immigrant while the deportation-based bar is still in effect, you may be able to arrange this by first completing USCIS Form I-212. Form I-212 is a request that the U.S. government lift the bar early and allow you to go forward with your visa application. Not everyone is allowed to use it; if, for example, you have committed murder or certain other crimes, this waiver is not open to you.
You will also need to submit various documents that explain and support your case, including records of your removal proceedings. These might be affidavits from people who know you, medical records, employment records, birth certificates of family members, and so on.
The I-212 instructions list a number of "favorable factors" that you should try to document in support of your case, such as evidence of close family ties in the U.S., hardship to your U.S. citizen or lawful permanent resident relatives or employer or to yourself, your reformation and rehabilitation, how long you were lawfully present in the U.S. and your immigration status during that time, your respect for law and order, your good moral character, your family responsibilities or intent to hold family responsibilities, the absence of significant undesirable or negative factors in your case, your eligibility for a waiver of other inadmissibility grounds, and the high likelihood that you will become a lawful permanent resident in the near future.
