回复：理论上来讲并不限制一个人拥有几份工作，但前提是得到

You must have a proper LCA filed for each location in which you will spend
more than 30 workdays in a one-year period. If USCIS looks at your
situation, for example at the time you ask for permanent resident status,
and notices that you have concurrent full-time H-1B petitions with LCAs for
different cities which are not in commuting distance of one another, I think
there will be a problem.
