Switching employer often on H1-B

Will switching employer often on H1-B have any negative impact as far as USCIS is concerned?

(I mean, switching employer by filing H1-B transfers often)

Thanks in advance

Technically, you can change any number of employers. But logically, USCIS may ask you for a reason. If your answer makes sense, they would allow you to continue to hop around. Once they suspect, you will be drowned in the RFEs.

What do you mean by they suspect?

Of course the reason for employer change will be for a better salary…

Suspect = In normal situation, folks wont hop too frequent. All you need to do give a reason that make sense. But law never prevent the number of employers one can be employed by.
