How a traveler prays for a long period

I live in Kuwait, and we have a house in Saudi Arabia. I come there once a year, approximately, and stay for two months. Should I shorten and combine the prayers, or combine or shorten only? If you consider Kuwait to be your home;Therefore: You are a traveler in your coming to Saudi Arabia, so you may avail yourself of the dispensations for travel. However, as long as you hear the call to prayer, it is obligatory for you to pray in the mosque. It is well known that one who prays in the mosque will not shorten the prayer, because the imam completes it, and it is obligatory for one who prays behind an imam who completes the prayer to complete it as well. But if you miss the prayer, you may shorten it. As for combining, there is no need to combine, because you are a resident. Likewise, you may wipe over your leather socks for three days, because you are a traveler, even if it is for a month or two months.
