Effect of immigration proclamation/executive order on green cards
I have a question regarding the impact of the recent Executive Order on my parents' greencard application, which is currently underway. I’m a US citizen (India-born, recvd greencard via EB category) and have sponsored the greencard application for my parents, who live in India, via consular processing. I-130 is approved, and we filed DS-260 and Form I-864 on 4/22 before EO was announced. Does the EO impact their case, or given it’s already in-progress (past I-130 approval), will it continue unaffected?
Can pending immigration applications be affected by changes in the law?
If new legislation proposed by Cotton and Purdue passes to remove the IR5 category (parents of USC), what happens to change of status (I-130/I-485) petitions in progress?
