Travelling before a visa appointment?

[hironbes]

Husband has a visa renewal appointment on October 2 in paris. Before that we are planning to spend a week in Greece to visit family. He cannot enter the US without having his visa stamped and renewed. This would be bad and awkward for his job if he missed the appointment.

Has anyone else scheduled personal https://19216811.cam/ https://1921681001.id/ travel for before their visa renewal appointment? Is this bad practice on our end https://19216811.cam/ https://1921681001.id/ ?

Looking for general insight, advice experience.
