Washington, Aug 26: US immigration authorities will soon require an in-person interview for certain applicants for green cards, a change that is likely to slow the process of obtaining one and may jam the already-backlogged visa application system, a media report said. The new requirement, which was confirmed on Friday by a spokesman for the US Citizenship and Immigration Services (USCIS), will apply to anyone moving from an employment-based visa to lawful permanent residency, Politico reported.
