Q
I do agree on the part that unused time can be claimed for future h1b, IMHO I disagree with the rest. These are the kind of things ppl end up with rfes, interviews, noids and mtrs. I have personally seen ppl going to interview, but almost each case was successul. Again that was just my opinion and you don't have to agree :-)
Just fyi, I tend to answer so that no risk by following my post.

also I use tablet to type . So generally I only answer the question, nothing else. And these all are just based on my knowledge and exp of more than a decade of my stay here :-) . I know people take all these info, and if they don't like it they can dump this info in garbage.
