To get a residency visa, you need the contract of your apartment OR a stamped rental contract (the apartment owner will have to do this for you), 2 passport photos and some copies of your passport (page with your photo and the page with the last entry stamp). In addition, you must exchange the amount of 85 US dollars (or the same amount in €uro) in a state bank. For this you will receive a special receipt on which your passport number and name are stated. Pay attention to this before leaving the bank. Banks that have always been recognized so far are the NBE and the AAIB. There may be others. You should apply for the new Visa 30 days after your last entry to Egypt. According to the current status, the visa can be overstayed for 14 days without incurring any further costs. After that, you have to pay penalty. To be 100% sure, you should inquire at your embassy or at the Hurghada "Visa Office".
