The South Portland man who is under federal investigation for possible financial ties to an attempted bombing in New York City is scheduled to make his first court appearance Wednesday, on claims that he overstayed his work visa.

Mohammad Shafiq Rahman, 34, will appear at the Boston Immigration Court via teleconference from the South Portland offices of U.S. Immigration and Customs Enforcement, court administrators said today.

Immigration Judge Francis L. Cramer will preside over the hearing at 1 p.m.

Rahman is a Pakistani citizen and computer programmer who lives with his American wife in a South Portland apartment. He was arrested May 13 by immigration agents as part of a sweeping investigation into a failed car bombing May 1 in New York City’s Times Square.

Authorities have said Rahman, as well as two other Pakistani men, helped transfer money that was used by the bomb suspect, Faisal Shahzad. But no criminal charges have been filed against Rahman, Aftab Khan, 27, and Pir Khan, 43, both of Watertown, Mass., and authorities have said it is not clear whether the men knew anything about the plot.
