Is it reliable to apply for immigration from an immigration agent now? Can't I apply myself?

There are good and bad intermediaries. What I can do for you is a good company. No matter how good the company is, it is useless to you.

Personal experience, even companies with good reputation do the same.

In order to judge and evaluate the work of an immigration agency, the most important thing is to know the immigration policy thoroughly. So no immigration company can cheat you. On the other hand, if you just want to spend money and give all your work to the immigration agent, then it is difficult for you to have a judgment.

My immigration started with an immigration company, but I gave up everything like this and almost lost my job. Finally, after I realized it, I thoroughly studied the immigration policy, and then sent an email to the embassy stating that I had cancelled the contract with the immigration company and handled it myself. I made all the materials myself and changed my passport.

Therefore, immigrants also apply on their own.
