You can use narrow, specialized terms to search the following databases and sites as you are searching the full text of the articles. For exact phrases use quotes to narrow your results. Add United States or US in your search to limit your results to articles that focus on US immigration policy for legal residents. Below are some possible search terms:
- "legal permanent resident" AND United States
- immigration policy AND United States
- permanent residents immigration AND United States
- citizenship AND United States
Add additional terms to your search such as economics, politics, or ethics to focus your research on more narrow aspects of the Spring Exercise. Another option to restrict search results is to change the default search from a keyword search to searching for terms within the abstract field only.
