I am about to leave USA for 3 months and I have been a GC holder for the last 3 years. I have worked for only 1 of the 3 years. Politically I am center left (not an activist) but I have made political contributions to the Dems while on GC and I was wondering if I will face any issues while re-entering the country. I was wondering if on re-entry if the CBP can use any hidden violation that I am not aware of right now to prevent my re-entry. The only thing I can remember as coming close it that in 2016 I mistakenly made a political contribution to presidential campaign unaware that without a GC I was not allowed to do that. When I realized my error I called up the political campaign number and asked for a reimbursement. Can small issues like this lead to any problem? Should I contact an immigraton attorney just for safety or am I being paranoid?
