Umrah visas are not issued after Ramadan. Pilgrims who go to visit during Ramadan must leave the country when Ramadan ends and cannot overstay this time. Basically, you have to leave on Eid or shortly a day or two after Eid Al Fitr. Individuals dependably inquire as to whether they can remain longer than Eid and I have seen examples where they booked their flights for seven days after the fact. Your Umrah visa rule explicitly says you should not spend Eid Al Fitr there.
The only people who can perform Umrah after Ramadan are GCC nationals; those with permanent residency or work permits and Saudis.This is because, to control the flow and make sure they are ready for Hajj. If you want to go for Umrah after Ramadan you will actually have to wait after Hajj.
