Who told you that the remaining quota for 2018 is only 50400 itas? Could you validate the info?
Last year 86K itas were given and this year 4% increment of the quota has been declared, so even if we assume 86K itas that will be given this year and 24.5K itas were already issued, still there are 61.5K itas are left for the year, which means 3843 itas per draw with 16 draws remaining in 2018.
Even if we assume that this year the ita that will be given is 80K which is almost a 10% decrease compared to the last year, still around 56K itas are left which accounts for 3500 itas on an average for the next 16 draws.
So, all in all, we should see 3500 itas to be issued at least for the next couple of months. Pls restrain yourself from writing infos that you are not sure of. thanks.......
