It’s illegal immigration that is completely ruining America today. As for legal immigration, there are plenty of checks and balances, especially on the financial front, that the consular office in the origin-country scrutinizes carefully. You can verify this by going to any foreign US consulate website, and reading the complex procedure for immigration.
With the illegals, however, the entire mechanism is destroyed. Even the lottery system for specific African countries, aids this.
As a legal immigrant who arrived in this country after waiting for two years, I can guarantee you I had to have a medical, submit biographical data, have a criminal background check, have fingerprints taken, have a COLLECT phone call from the US. consulate in Vancouver to advise me when I could come to Vancouver to complete an interview (there are only two Consulates in all of Canada which issue financee Visas) and pay $2,000 in fees as well as exactly $95 fees in U.S. dollars before even entering the U.S. Consulate in Vancouver I was also not allowed to take my 1/3 inch insulin needles into the Consulate with me. Upon arrival at the Rooseville border crossing in MT, I had to use the bathroom, but was not allowed out of the vehicle to use their porta potty until their border official decided I could do so. We were finally allowed inside the office and sat there for over two hours while the customs official did the paperwork to accompany the K-1 (fiancee) visa on July 23, 2002. We married July 26, 2002 and I officially became an immigrant in the U.S. Until I said “I do” I was only a tentative immigrant, in the eyes of of the old I.N.S. Now, according to the director of the Health and welfare dept in Idaho the holder of a K-1 Visa is only allowed into the U.S. for a period of 90 days to marry a U.S, citizen. It is so nice to know he can use google to find that information. (sarcasm intended)
