Trending @Infosys; JL5 promotion eligibility

Hi all. I am currently in TA role with 6.25 years of total experience. I completed the BCEP certification by Feb last week this year. My manager informed me that I have been nominated for promotion to TL role but I have not received any mail regarding this. When can I expect the promotion to take effect and get the mail for confirmation considering my BCEP completion date? Thanks
