Dear Ms. Liwer-Stuip,
Thank you for posting your request on History Hub!
If you have not already requested it, we suggest that you submit an Index Search request to the US Citizenship and Immigration Services (USCIS) Genealogy Program. There may be a record that the Immigration and Naturalization Service (INS) created for Abraham Liwer. It could include a Visa File and/or subject correspondence file. Please include any known name or date of birth variants available to ensure a successful request.
We also suggest researching how Curaçao visas were handled within the US. Please begin by emailing the US Citizenship and Immigration Services (USCIS) Historical Library at email@example.com to inquire about any documentation they may have regarding administrative policies of the Immigration and Naturalization Service (INS) related to Curaçao visas. Also inquire about possible detainment of those arriving in the US under such specific war-time visas. Please frame the question more broadly than using your grandfather’s information in order to gain an understanding of what the experience of those with Curaçao visas may have been like.
We hope this is helpful. Best of luck with your family research!
