A woman who has had 10 husbands admitted that she wed one man in return for cash and helping him get citizenship, prosecutors said on Friday in a Bronx courtroom.

Most of her husbands immediately applied for citizenship and some, when denied, divorced her and refiled with different wives, prosecutors said.

And one husband, from Pakistan, was later deported in connection with terrorism threats against the United States, the authorities said.

The woman, Liana Barrientos, is still married to him — and to three other men, a prosecutor said.

The details behind Ms. Barrientos’s matrimonial habits and choice of husbands began trickling out on Friday as she was arraigned on fraud charges in State Supreme Court. Ms. Barrientos, 39, pleaded not guilty and stood tight-faced beside her lawyer, Christopher Wright, as an assistant district attorney, Jessica Lupo, described her case.
