You're getting this backwards. Claiming most asylum refusals are due to fraud without anyevidence is the opposite of common sense
Also having an economic as well as other reaspns to immigrate does not mean someone isnt a qualified refuge or or not facing persecution or are committing fraud.
Taxes are complicated just like our immigration system. Many people make innocent mistakes every year, most people don't want IRS to come down as hard as they can on every innocent mistake by treating it as fraud without any proof. They expect corrections and if necessary small fines.aw
