H1B, H4 Visa

Hi Folks,

I attended H1b visa stamping couple of days back and I have got 221g white slip. Initially I thought that was given due to a wrong answer that I provided but not that reason. Actually in my ds160 my work started from my employer is stated as August 2015. And my graduation is done by December 2015 which is 4 months of CPT internship. And later I got 3 years of OPT thats means 36 months of work authorization. But after December 2018 my OPT was completed so I joined a CPT college and worked 40hrs CPT until today that means 8 months on CPT in 2019. So all combined it is 48 months that means 4 years of experience I worked with my employer in USA. So consulate officer asked me how many years have you been with your employer as mention in ds160 I said 4 years. And he asked me as you said you are done your masters by December 2015 how come you work for your employer from August 2015. Then I said it was my internship with him. He said ooh ok ok, and then he started counting months but he is getting just 40 months count instead of 48 months because he didn’t able to ask me on what status you are in 2019 after your OPT and how did you work. And I didn’t even said him I was working on CPT from jan 2019 to present because again it might be an excessive issue. So then he counted those months for couple of times and asked me have you worked on h1 then I said no sir on OPT. So later he gave 221g because he was not able to understand the complete 4 years count. So will it be a problem in the administrative check and is there any person who has the same issue and how long does it took.

Thanks
