H1B extension fee on I-140

[luck2u]

Can anyone tell me the H1B fee when we're applying for extension on I-140? Is only base filing fee ($325) apply for H1B or anything else? Thanks in advance!

It depends..If this is your FIRST extension with the SAME employer, you have to pay the $1500, if SECOND extension with the same employer you only pay $325...Hope this helps...
