新Proclamation针对J签证范围，求大佬解答

Proclamation原文如下：

Sec. 2.  Suspension and Limitation on Entry.  The entry into the United States of any alien seeking entry pursuant to any of the following nonimmigrant visas is hereby suspended and limited, subject to section 3 of this proclamation:

(a)  an H-1B or H-2B visa, and any alien accompanying or following to join such alien;

(b)  a J visa, to the extent the alien is participating in an intern, trainee, teacher, camp counselor, au pair, or summer work travel program, and any alien accompanying or following to join such alien; and
.google  и
(c)  an L visa, and any alien accompanying or following to join such alien.

Sec. 3.  Scope of Suspension and Limitation on Entry.  (a)  The suspension and limitation on entry pursuant to section 2 of this proclamation shall apply only to any alien who:

(i)    is outside the United States on the effective date of this proclamation;

(ii)   does not have a nonimmigrant visa that is valid on the effective date of this proclamation; and

(iii)  does not have an official travel document other than a visa (such as a transportation letter, an appropriate boarding foil, or an advance parole document) that is valid on the effective date of this proclamation or issued on any date thereafter that permits him or her to travel to the United States and seek entry or admission.

所以问题是，
1、Research scholar的J1是否受影响？还是说具体执行层面上，海关看见是J1，就会一刀切地全部禁止？
2、section 3这(i)、(ii)、(iii）的关系是交集(and)还是并集(or)？
如果是交集，那么受影响的只有“目前在美国境外”且“没有有效签证”的人。
.google  и如果是并集，那么受影响的就是“目前在美国境外的一切人”，以及“没有有效签证的人”
所以到底是怎么样的？求大佬解答！我不想到了机场被遣返...

既然他明确列出了这些类别，应该不会影响research scholar（律师twitter也说过不会影响）。海关怎么做谁也没法打保票
2
大家都说是交集。实在不放心的话，最近各种签证回来的人应该不少，可以等几天，看看dp

research scholar不在禁令范围内地话签证还是会照常审批的吧？
