What was required of immigrants processed at angel island but not those processed at Ellis island?

Excessive interrogations and crosschecking from other family members was required of immigrants processed at angel island but not those processed at Ellis island.

Explanation:

The immigrants at Ellis Island were treated more fairly as compared to those that tried to immigrate through Angel Island. The interrogations at Ellis Island were small which were preceded by a minute's worth of physical checking and evaluation, which needed to be passed to move onto the part where the inspector checked their documents and cross-questioned lightly.

The whole process took way less than it took on Angel Island. At Angel island, the physical evaluation process was the same, but they had to go through a gruelling amount and difficulty of questions, after which they were verified from any family members that already lived in America. Through Angel Island, the whole process of immigration took about months of preparation in advance, and any difference in the testimony of the family members and the applicant led to excessive difficulty in the procedure and risked deportation as well.
