The E.T. Guy (Office Aliens Book 1) by V.C. Lancaster
It's 2266, and Lois Kennedy is an Intake Officer for DETI, the Department of Extra-Terrestrial Immigration.
Zir is a refugee from the planet Teiss, working in DETI's I.T. department.
Lois and Zir just can't get along. As far as she's concerned, he's rude, abrasive, and condescending. She wants nothing to do with him. So why does he never leave her alone? He must be crazy if he thinks there could ever be anything between them... right?
