CPT导致的COS失败会影响之后的CP么

如题，如果因为cpt导致了change of status失败，那就必须离境签，那这个change of status的失败会对consular processing有影响么


还是说用CPT的人最好直接跟律师说好用consular processing以降低风险

PS：现在跟律师说想改 还来得及么现在。。

请参考IG给出了例子：
“Day 1 CPT”:

An F-1 student completes his studies, graduates in December 2014 with a master’s degree in a STEM field, and obtains one year of Optional Practical Training plus two years of STEM OPT. During this OPT time, the student was unsuccessful in the H-1B lottery. In August 2017, the student enrolls in a second master’s degree program that provides for CPT right away so that he can continue working. In April 2018, the student is sponsored for an H-1B visa requesting a change of status from F-1 to H-1B and is selected in the lottery. In December 2018, an RFE is issued on the pending H-1B petition requesting documentation that the CPT was properly authorized. Based on the information obtained through the Request for Evidence, USCIS approves the H-1B petition on March 15th, 2019, but denies the change of status due to the use of CPT at the same degree level. There has now been a determination made by USCIS that a violation of status has occurred and the student has been out of status since August 2017 when the CPT began. Further, under the memo, he began accruing unlawful presence on August 9, 2018. Since he did not receive the decision until March 2019, this student will have unknowingly accrued more than 180 days of unlawful presence. When the student now exits the United States, he will be subject to a 3-year bar, meaning he will be ineligible to obtain the H-1B visa stamp based on the approved petition and ineligible to return to the U.S. for the next 3 years.

全职day 1 CPT 今年以求保险的话应该选择consular processing，避免unlawful presence的180天。不止是是否影响cp的问题，而是有没有累积非法逗留的问题。
例：18年9月入学使用CPT，19年4月H1B抽中，7月得知CoS被拒，意味着USCIS认为从18年9月到19年7月之间为非法滞留，你必须即刻离境，同时因为非法滞留超过180天，将有三年bar，无法再次获得签证。

这点我觉得移民律师应该很清楚才对，要是他没有跟你讲今年是CoS还是CP的话……我觉得他不太qualify当移民律师啊，其他方面都要盯紧点才好。

补充内容 (2019-3-8 06:03):
另外关于unlawful presence的memo去年（2018）八月才生效，加上180天的话严格来说今年2月之后才会看出影响，目前并没有那么实际例证，USCIS的执行力度为何尚不清楚。相信今年H1B过后会逐渐明朗。
