How could he be found inadmissible if he did not already leave the U.S.? Removability is in section 237 of the Act, and inadmissibility is in 212 of the Act. They are not the same, people removable may not be inadmissible and vice versa.
The above is intended only as general information, and does not constitute legal advice. You must speak with an attorney to discuss your individual case.
Inadmissibility: Section 212(a) of the INA lists grounds of inadmissibility. These grounds apply to anyone seeking admission to the U.S. either as a permanent resident or as a nonimmigrant. Admission means the “lawful entry of the alien into the United States after inspection and authorization by an immigration officer;” and involves physical entry to the U.S. at a port of entry (INA 101(a)(13)).
Deportability: Section 237 of the INA lists the grounds of deportability. The INA still uses the word “Deportability” to define the grounds on which someone can be removed from the United States,although the name of the proceedings are no longer “deportation proceedings” but “removal proceedings.” If a foreign national is deportable, it means he can be placed in removal proceedings by Immigration Customs and Enforcement (“ICE”).

I agree with my colleagues, this person needs to hire an experienced immigration attorney if he has been denied entry or paroled into the United States.
