Jumuah

Delaying the four sunnah before jumuah while in the haramain

Q: My family and I will be going for Umrah this month. My question is around the 4 sunnah of Jummah. 

We know that the azaan is given before zawaal and we cannot perform these 4 rakaats. Do I perform it immediately after the 2 fardh or do I read the 4 sunnah after the fardh, then the 4 sunnah that I missed, then the 2 sunnah and then 2 nafl?
