The fifteenth amendment impacted the African-American experience because it was unheard of in the South due to Jim Crow laws. Only African American men had the right to vote. The significance of this amendment was to overrule the state's laws on voting.
The 15th Amendment allowed all men in the United States the right to vote regardless or race or previous status as a slave. This, in theory, should've allowed men of color to easily vote, but this was not the case. Polling places instituted things like literacy tests and polling fees which made it difficult for African-Americans as not many had sufficient education or income as they had only recently escaped servitude. Overall, the 15th amendment provided little to no benefit to African-American men, and no benefit to African-American women as they still could not vote at all.
The Vietcong set up checkpoints around the nation, so that would've definitely been a literal and figurative roadblock to any refugees. Hope this helped.
