What forms do I need to petition for my husband who entered to U.S. illegally?

Unfortunately, not even being married to a U.S. citizen and having a U.S. citizen child can save an individual who entered the United States without inspection from having to leave the United States and having to seek admission. This process is referred to as consular processing. In addition, as your husband has accrued more than one year of unlawful presence, he is likely going to become subject to a one year bar of inadmissibility during which he cannot accept any immigration benefits. There is a waiver available for this particular bar, but it will be necessary to show that you will suffer extreme hardship if forced to either (1) remain in the U.S. without your husband or (2) accompany him to his home country. Even so, the waiver can take up to a couple of years to process, and even then, there is no guarantee of success. The typical forms that will need to be used in this type of case are the I-130, I-864, DS-260 and the I-601 waiver. However, before taking any actions, I implore you to speak with an immigration attorney about your case. In the first consultation, give the attorney all of the details about your husband's case and be 100% ap front and honest about everything. Only then will he or she be able to give you an optimal evaluation of your case.
