我只大致翻译，具体以英文为准。

Under certain conditions, applicants who are renewing a nonimmigrant visa may not be required to come to the Consular Section to apply. Qualifying applicants may use the Visa Renewal - Courier In Documents selection on the Trip Purpose Selection Page to submit their complete visa application via Loomis. Please read below for details and qualifications.
在满足特定的条件时，非移民签证申请人可能(may not)不再需要前往使馆申请。满足条件的申请人可能可以通过Loomis邮递文档的方式来提交他们的签证申请。


This interview waived exemption applies to applicants renewing their visa and who meet ALL of the following qualifications:
免面试必须符合下面的全部条件：

The applicant resides in Canada.

申请人必须是加拿大居民

Note: Applicants with Canadian student permits, Canadian work permits, or Canadian permanent residency shall be considered as residing in Canada. Applicants with Canadian visitor permits shall not be considered residents.
注意：学习许可、工作许可和PR都算加拿大居民。如果是访客签证将不被考虑是加拿大居民

The applicant previously held a non-immigrant visa and is applying for the same classification of visa except Treaty Trader/Traty Investor (E1/E2), Australian Worker (E3), Temporary Worker (H2), Intra- Company Transfer with Blanket Petition (L), and Refugee/Victims Visas (T, U)
申请人只能续签同类型的非移民签证，除了E1/E2,E3,H2等等。

The visa expired less than 12 months ago and is in the applicant’s possession.
之前的签证不能过期超过12个月。我不确定possession的具体含义是啥，我自己觉得可能是你必须能出示这个过期的签证(在这本护照上，或者在旧的护照上)。

If the applicant has been refused a visa, must have been subsequently issued a U.S. visa and is renewing that previously issued visa.
如果之前被拒签过，那么必须最终核发了签证，并且是续签之前核发的这个签证。(这个略难翻译，领会精神，但是这条跟下面的情况中有一条矛盾，我不知道我的理解是不是对的，这条翻译仅供参考)

The interview waived exemption does NOT apply to applicants who:
以下情况的申请人不能免面试

Hold a passport from Cuba, Iran, Syria, or Sudan
古巴，伊朗，叙利亚和苏丹的护照持有人

Hold a visa previously annotated “Clearance Received” or “Waiver” indicating a previous waiver of ineligibility
之前核发的签证上，annotation下面有写Clearance Received的或者Waiver的

Have checked “yes” to any of the DS-160 security questions, including “have you ever been refused a U.S. visa.”
如果你填ds-160的时候，安全问题有勾yes，包括之前是否被拒签过勾了yes(这点跟上面的最后一条貌似有冲突)
