@pk , Yes I moved to US from India in 2012 for PhD. There have been no gaps, I have F1 extended. I graduated from the University in August, 2018 and since been working on OPT and subsequently STEM-OPT. I have been employed by university from 2012 -May 2018 by the university. In between I had an internship in 2017-outside university.
My assumption is my employer should have withheld my contributions to FICA for 2017 summer internship and the employment after graduation in August, 2018. But the employer did not, so I am trying to pay my share. Any suggestions?
