IHA shall respond within 12 to 24 hours, and send you a welcome link to click, this link shall be active for few hours and shall be reset. So, kindly watch your email inbox . Once this link is clicked, you shall have a waiting period, where an admin shall verify your phone number across registration form, and allow entry to the group. Only the phone number in the registration form shall be admitted as a member to prevent the group from Bots/ Scams. Apologies for such Exhaustive Process.
