USCIS has posted a new Web page on the H-1B and L-1 fee increase required by the Consolidated Appropriations Act, 2016 (Pub. L. 114-113). Pub. L. 114-113 requires certain petitioners to submit an additional fee of $4,000 for certain H-1B petitions and an additional $4,500 for certain L-1A and L-1B petitions.
What kind of problems can employment-based nonimmigrants (H-1, L-1, E-1, E-2, E-3, TN) face during reentry?
I think this question is most relevant for H-1 holders, but other employment-based nonimmigrants may also note the general principles here.
