I have applied for J1 research scholar Visa after getting my Ds-2019. I got my B1B2 issued last year and over the last 12 months I have spent 9 months in the US in three different trips all for taking exams, observershipsand to attend interviews ( one for 2 months, 6 months and 1 month with no overstay- I was always stamped 6 months at Port of entry) . Will my history of travel on B1B2 affect my chances of getting J1 approved? Should I delay my J1 interview by a month or two? Any advice will be helpful. Thank you
