only uscis officials can judge if you are qualified.
some comments/suggestions:
J1: you may need to get a waiver if you have 2-y-r home residency requirement.
publications are good, but citations are more important now.
membership: serve on committee on a prestige association may quanlify
best paper awards: awards should be at national level and above.
need to judge others work such as manuscripts and proposals
perhaps the responses are too late for you. good luck,
