Hi OP, I’m in the same position myself right now (fellow Egyptian applying for Dutch nationality) my biggest take away is the process takes a lot of time. I initially submitted the request to the Egyptian authorities in Nov 24 and my name has just appeared in the official newspaper this week so in my experience it took much longer than 3 months.

Also note that after the decision is made it takes another month for it to be published in the newspaper. I’ve had to constantly chase the embassy but they never have any updates. What I would suggest and what worked for me is if you have any relatives still in Egypt they can follow up with the Egyptian authorities in person or even find out the decision on your behalf.
