I am planning to travel to India from end December, 2017 to end of Jan, 2018. I currently working OPT (stem extension) and my company is planning to apply for H1B next year in April 2018. My opt stem extension expires Feb 2019 and my F1 visa expires in Dec 2018. Recently I received an email from the immigration lawyers strongly recommending not to travel 90 days within filling visa appplications (not to travel outside US after Jan 1st, 2018). Can travel be a problem while re-entering US or while applying for H1B next year? Also can the travel be questioned while stamping for H1B visa in the future? Thanks!
