Answer:
French (and Irish?) immigrants.
Step-by-step explanation:
The alien laws were aimed at French (and Irish immigrants, who were mostly considered pro-French). The Alien and Sedition acts gave more powers to the government to deport foreigners and make it harder for new immigrants to vote. They also restricted the activities of foreign residents in the country, also limiting their freedom of speech and press. This was mainly because of widespread fear of an imminent war between America and France.
