Thanks Danphe. I hope so too. but as I mentioned his case may be different from yours. He is not in legal status his visa and 1-20 both expired. He could not renew extend those in the US. He just want to have a peace of mind when he travels to Nepal

Would you or others please provide me some credible source for this that he will not require transit visa. he will like to print that and take with him when he travels.

Anybody who travelled via Paris please suggest.
