vsc_485 said:If you look at the USCIS's New Immigrant Welcome guide, it clearly states that you may loose your Green Card (or PR status) if you obtain Permanent Residency in another country. According to USCIS, by becoming PR of another country, it implies that you do not fully intend to be a Permanent Resident in the United States. This is similar to staying abroad for more than 6 months without obtaining prior permission.
There is a different between "obtaining PR permit/card for another country" and becoming or obtaining PR status of another country". There is nothing wrong to apply for perm residentship for another country. But the problem arises when someone actually becomes PR or "obtains PR status" at another country. For example, someone can be approved for Canadian PR and sit quiet in USA. That's not a problem. But if he/she enters Canada in PR status, that's where USCIS gets issue.
