better to get a ECNR. it actual relies upon on the guy who's on the immigration counter. ECR is uncommon and officer can argue on the inspiration that the guy showing that he'd traveling SG or cleared international locations yet might visit a diverse u . s . a . which isn't cleared. ECNR does not take multiple time and at max at some point.

no its not requried. after OCt 2007 It removed by the govt.....anyone can stay upto 6 month outside india on a touirst visa

The proper visas are what is required for these countries in question.
