The DHS press release[1] has more details. Link to the proposed rule on reginfo.gov[2].
In short, this rule allows spouses of H1B holders to work, provided the H1B holder has an approved I-140 or has their H1B extended beyond 6 year limit under AC21. Notice that this rule is very specific and does not cover all H1B holders.
If you're a Firefox user, install RefControl, and then spoof the referer for any request to this website as "http://www.google.com/". This gets around the paywall; I just tried it. This works with most paywalls.
On the other hand, I don't think it should be permitted to post articles here that are behind a paywall. That's just my opinion though.
Not quite. Spouses of people who are working in America on a H1-B visa and have applied for a green card or extended their visa are allowed to work themselves. That is a much smaller pool than people on H-1B visas.
Still not quite, because they are not automatically allowed to work. They have to request employment authorization and who knows what other criteria may be imposed at that time.
