Advance notice for N-400 citizenship process appointments re overseas trips

[rwsh]

I understand that short overseas business trips are allowed during an N-400 naturalization process (unlike during my Green Card application when I had to “apply for permission”; always granted). However, I do not want to jeopardizes my application by missing the fingerprint appointment, interviews etc. Please does anybody know how much advance notice the USCIS gives when sending out the notices of these appointments? Days? Weeks? Many thanks. William, San Antonio.

I think it depends on the service center. VSC gave us about 2 weeks for FP, around a month for Interview and 2-3 weeks for oath.
