Conditional Permanent Resident

Conditional Permanent Residents must file Form I-751 90 days before the end of their two-year card expires, otherwise they will face the denial of their application and possibly even deportation.

Immigrants who are accorded Conditional Permanent Resident status are essentially undergoing a two-year "probation" period during which time they must prove that they are genuine applicants, rather than illegal immigrants.

The purpose of immigration Form I-751 is to remove the conditions on residence for immigrants who gained their status through marriage to a US citizen or Permanent Resident. But are divorced or widowed Conditional Permanent Residents allowed to file this form?
