Which is better for American talents to immigrate?

If your application for immigration to the United States has just been rejected, and then you start applying, you will still be refused a visa. No immigration agency can help you solve it. You should temporarily stop applying and analyze the reasons for your rejection in detail. Then, after three or five years (from the day when the US Immigration Bureau sent you a letter of refusal), you can succeed again. If you apply again immediately, or submit your application in a year or two, you may be refused a visa.
