Hello. I have an approved i140 and my wife's h4 ead is valid. My h1 renewal is in process and my LCA is in review for my h1b renewal and my h1 is expiring in July 2017. I want to apply for my wife's h4 and ead extension by myself as the lawyer is charging $1000 for legal fees alone . The question is, Can I apply ONLY after I get a new receipt number for h1b renewal? Can I apply for spouse's ead extension along with h4 renewal (i539?) Applying premium is out of the question as my application won't be ready by April 3, 2017 Thanks!
