Hello Raz,
I don't know if you followed the latest news on Nicaragua. We have some political and social turmoil here, and things do not seem to be solved in the short run: Almost daily demonstration marches (mostly peaceful), but also roadblocks and probably a nationwide strike within the next days. Things are imprevisible.
More than 70 protesters were killed (shot in head and chest), about 600 wounded and many "disappeared".
I advise you to check out some news. For immigration though you find all infos - in Spanish - on the website of the Nicaraguan immigration authority:
