In Aliens V, the Preadtors come in H1B Work Visas to hunt in the local USA, the Xeno Bug Aliens also come in on H1B Visas due to Corporations forcing the government to increase the work visa quotas. Ripley is assigned to the HQ of the parent office that funded the space programs.

In Aliens VI, they find out that there is a much more deadlier threat than the Aliens and Preditors, it is the Pointy haired Bosses that run the Corporations, and they are ready to downsize!
