@ravit.thapar I believe we chose option(b) but it should not matter as option (a) is applicable as well. We forgot to file 8843 for spouse but I hope it is fine as they are claimed as dependent. I thought e-file was not available last year so manually filed. I used services of HR Block for peace of mind (rejected filing, amendment, audit protect) but they are useless...I had to teach them how to file my taxes to get maximum benefit. But definitely helped for ITIN.
My suggestion is to either approach some tax prof who works with NRIs for this year and the first year you might get H1 as its a little complicated. They will know how to get maximum benefit. If you want to file yourself, read pub519 and others that are applicable for you to get more insight. And ofcourse ask question here.
I wish turbotax supports NR filings but I really appreciate their help forums like this. SprintTax is the worst software all over. TAct helps a little but doesn't suit your needs either. Good luck!
