I travel to EU for work for two or three weeks at a time for the last few months. I have a GC, which I'd like to maintain obviously and I would also like to apply for Citizenship without delays.
“Continuous residence” means that you have not left the United States for a long period of time. If you leave the United States for too long, you may interrupt your continuous residence.
They look at trips longer than 6 months at a time, so your short trips shouldn't cause any problem when it comes time to apply for citizenship.
Do not go where the path may lead, go instead where there is no path and leave a trail. (Ralph Waldo Emerson)
Generally, you can't have been out of the US for more than 30 months total in the 5 years prior to applying for naturalization - 18 if applying under the 3 year rule (so half).
If you work for a US Company and it's them that's sending you for the short trips, it shouldn't be any issue at all.
You just have to show that you have an unrelinquished primary residence here. I presume you stay at hotels while traveling overseas, not at a residence you own? If the question comes up, show your hotel receipts that show that you travel on business.
