@irene06 All good suggestions from @lutra. I’ll add that if you have any power bricks, now is the time to charge them and take them with you. They will help you get through any periods when you don’t have access to charging. Also, having energy (food) bars with you may help sustain you if there are long waits in the queue. I wish you the very best under the circumstances. Stay safe. May the courageous fighters of your nation prevail in securing your freedom and independence.
