Here is the Final Rules from US DHS (from website):
Effective January 18, 2009, the following additional non-U.S. citizens will be required to provide biometrics when entering or re-entering the United States:
* Lawful permanent residents of the United States (LPRs);
* Persons entering the United States who seek admission on immigrant visas;
* Persons entering the United States who seek admission as refugees and asylees;
* Canadian citizens who are currently required to obtain a Form I-94 (Arrival-Departure Record) upon entry or who require a waiver of inadmissibility to enter the United States (this excludes most Canadian citizens entering the United States for purposes of shopping, visiting friends and family, vacation or short business trips);
* Persons paroled into the United States; and
* Persons applying for admission under the Guam VWP.
Now, my question to pjiang and other maestros is:
what if the LPRs have prior arrests or minor offenses which had been inspected and adjusted by USCIS and granted LPR status---will CBP refuse the entry of these LPR to US?
